BACKGROUNDDirectional drilling is a challenge due to shortages of skilled workers and the level of difficulty associated with directional drilling. Poorly drilled wells cost oil companies millions of dollars each year. Directional drilling programs like WINSERVE™ provide an interface for entering survey data obtained from survey sensors in the drill string, and for performing calculations associated with drilling. Other programs have been disclosed for steering a drill string through the earth based on sensor feedback. Remote and local operation of drilling is possible with various programs.

In various embodiments, there may be included any one or more of the following features listed below.
Well Monitoring: various embodiments of the systems and methods are set up to monitor and ensure that any well that is run is drilled as per the predetermined well parameters and trajectories. This may be accomplished through a standalone wireless system on location that is in communication with a central main server monitoring system that enables oil company executives and supervisors to monitor the well bore progress.
Self-Supervision: various embodiments of the systems and methods give all personnel both on and off the location instant feedback and red line warnings acting as a self-supervising system for the well relating to well trajectory, bit, motor and overall drilling performance and as soon as the predetermined well parameters are breached the system instantaneously sends warning alarms to all personnel on and off location that are monitoring the well.
Safe-Guard Warning System (phase #1): in some embodiments a red line safe-guard warning system is set up in a two stage process when one predetermined well bore parameter is breached a single warning will be sent to everyone on and off location monitoring the well performance allowing the operator on location to evaluate and correct the issue at hand.
Safe-Guard Warning System (phase #2): When related red line warnings are received in two back to back surveys or two related predetermined parameter red lines are received within the same survey the system will prompt the operator to re-plan and re-evaluate the well trajectory by locking out the operator from entering any new surveys and send out a continuous warning signal to all personnel both on and off location that are monitoring the well performance until all personnel acknowledge that the second red line warning was received.
Survey Lock Out: various embodiments of the systems and methods incorporate a survey entry lock out system that remains in place until the well drilling performance is re-evaluated or re-planned and accepted by an oil company representative on the location or remotely by an oil company drilling superintendent through the system's active acceptance coding system set up at the beginning of each well.
Stop Survey Safe-Guard: various embodiments of the systems and methods incorporate a safe-guard self-supervision system that gives the oil companies the necessary information to drill the well properly within the original predetermined well parameters as set out by the oil company. Thus, the oil company is allowed to monitor the well performance on a continual basis with stop survey parameters in place to give the oil company the needed time to evaluate the drilling performance, the drilling equipment being used to drill the well, the well proposal and re-evaluate the drilling process as a whole including men and equipment allowing them to address any issues that may have arose.
System No-Fault Safe-Guards: various embodiments of the systems and methods have numerous safe guards in place to ensure that no oil company can place blame on the system if a well goes sideways. Numerous safe guards are in place to ensure that the system does not go down; however, if some unforeseen event does shut down the system the oil and directional representatives on location simply revert back to drilling the well in the same manner as it is being drill now, but without the system to monitor the well's performance.
Auto Calculate (data templates): various embodiments of the systems and methods incorporate auto calculate data templates that automatically assesses the well bore positioning for each and every survey entered based against the predetermined active well plan in use and instantaneously calculate what corrections have to be made to keep the well bore on track, for example based on slide seen, tool face drill off, percent (%) of slide in build/drop, percentage (%) of slide in turn, slide (unseen) under the survey point, tool face slide (unseen) under was set at, target number well coordinates that are being calculated against, the book value slide factor, the survey point slide factor and an average slide factor. The data templates may be categorized as Drill Down/Vertical, Build Section and Lateral Section.
Auto Well Bore Positioning: various embodiments of the systems and methods automatically assesses the well bore positioning for every survey entered based against the predetermined active well plan and the active window parameters in use and instantaneously display the results on the program header encompassing for example True Vertical Depth (Tvd), Inclination, Line, Azimuth and the Vertical Section (VS).
Proximity Plots: various embodiments of the systems and methods plot each survey against the predetermined active well plan and window parameters in use and automatically display the well bore positioning relating to both in relation to Tvd, Inclination, Line and Azimuth. The proximity plots allow the operator to scroll through the survey file to view the well trend as it is being drilled.
Desk Top Graphs: various embodiments of the systems and methods incorporate Desk Top Graphing allowing all personnel both on and off the location that are monitoring the well to graph out any and all the aspects (6 graphs per set) relating to the drilling of the well to enable all involved to view and make well informed decisions. Various embodiments of the systems and methods allow the operator to graph out for example day, night, 24 hour, overall well, Bha #, bit manufacture, bit type (coding), bit type (pdc, tri-cone), motor setting, all Bha's, motor/bha output, parameters (survey %), parameters (# surveys), time break (# hours), time break (hours %), rotate vs. slide (ROP), meterage vs. percentage, slide/rotate/lost tool face (%), average connection time, slide vs. rotate comparison (%), planned vs. drilled off (tool faces), and other parameters. In some cases everything that the program data base has recorded and stored can be graphed allowing the operator to view the information as a comparison through the desk top graphs.
Slide, Rotate Control: various embodiments of the systems and methods incorporate a slide, rotate control enabling the operator to get an actual rate of penetration (ROP) comparison for slides vs. rotates vs. lost tool faces vs. drill times in an exact time logging for all these aspects.
Tvd, Inclination Calculator: various embodiments of the systems and methods incorporate a Tvd, Inclination Calculator enabling the operator to calculate the necessary inclination to rise or drop a given distance over a given distance or to calculate the distance that will be raised or dropped over a given distance at a given inclination.
Interpolation Screen: various embodiments of the systems and methods allow the operator to interpolate and insert a survey with a comment into the active well survey file at any time.
Enter Survey: various embodiments of the systems and methods prompt the operator to enter the actual hole depth then automatically calculates the survey depth based on the Bit to Sensor distance that is entered in the Bha Information Template allowing the operator to cross reference the hole depth as a safe-guard eliminating the human error factor that arises from this calculation being done manually.
Wire-Less Communication Automatic Well File Down Load: In some embodiments, once the location sever establishes communication with the main server the main server automatically down loads the necessary well files.
Automatic Report Emailing: various embodiments of the systems and methods incorporate an automatic report generating emailing system based on time, reporting needed and recipients.

Directional drilling began in the early 1900s with slanted wells and eventually expanded in the 1970s to full horizontal wells. Wells are drilled directionally and horizontally for several purposes, including a) increasing the exposed section length through the reservoir by drilling through the reservoir at an angle or horizontally, b) drilling into the reservoir where vertical access is difficult or not possible, for example an oilfield under a town, under a lake, or underneath a difficult to drill formation, c) allowing more wellheads to be grouped together on one surface location to allow fewer rig moves, less surface area disturbance, and make it easier and cheaper to complete and produce the wells, d) drilling along the underside of a reservoir constraining faults to allow multiple productive sands to be completed at the highest stratigraphic points, and e) drilling from a safe distance a “relief well” to relieve the pressure of a well producing without restraint (a “blowout”).
Directional drillers are given a preset well path to follow that is predetermined by engineers and geologists before the drilling commences. When the directional driller starts the drilling process, periodic surveys are taken with a downhole instrument to provide survey data, for example inclination and azimuth, of the well bore. These surveys are typically taken at preset intervals allowing the directional driller to make changes or corrections to the angle or direction as needed to maintain the well bore preset trajectory. Drilling into target zones laterally from surface locations requires careful planning, design and supervision and can be time consuming and costly. However, directional drilling is valuable because it can reduce the environmental cost and scarring of the landscape. Because of these and other benefits the percentage of well bores drilled in this manner has increased from under 2% in the early '90's to over 70% to date.
Various methods are currently used to monitor and carry out directional drilling operations.
Mud motors. Mud motors are positive displacement motors (PDM) that offer steering capability and with it directional control. Mud motors are slid into the formation. Slide drilling refers to drilling with a mud motor rotating the bit downhole without rotating the drillstring from the surface. The bottomhole assembly (BHA) is fitted with a bent sub or a bent housing mud motor, or both, for directional drilling. The operation is conceptually simple: point the bent sub and the bit in the desired direction. Without turning the drillstring, the bit is rotated with a mud motor, and drills in the direction it points. When the desired wellbore direction is attained, the tool face is set to zero and the entire drillstring is rotated and drills straight rather than at an angle. By controlling the amount of hole drilled in the sliding versus the rotating mode, the wellbore trajectory can be controlled so that a curve of any inclination and/or azimuth can be obtained. In comparison to rotary steerable motors discussed below, mud motors are cheaper to operate and can achieve more severe doglegs.
Directional Drillers on Location. This method of directional drilling is the most common and widely used method of directional drilling in the industry. Directional Drillers are dispatched to the location to work on site and are charged with the task of monitoring the well bore progress according to the predetermined well plan trajectory, doing the mathematical calculation to achieve the target and to keep the well bore on track, relaying instructions as to what well bore corrections have to be carried out to the rig driller, assisting the rig driller when needed (steering to make well bore corrections) and supervising that the instructions are carried out effectively and efficiently. The directional drillers on location also are responsible for communicating the well bore progress and any issues that may arise that may jeopardize the well bore integrity to the oil company representatives on location (company man, geologist), to the oil company head office when necessary, and to the directional service company coordinator they may be employed by or subcontracted to.
Since the inception of directional drilling trained directional drillers on location was and still is the norm to get these directionally and horizontally drilled wells drilled. This approach is and was the logical progression for industry, take experienced drillers off the rig floor with extensive down hole experience (10 years plus), some sort of formal education or mental aptitude and communication skills and then properly train them in the art of directional drilling. This way the oil company and directional service company that was contracted to do the work had directional supervision on location that could carry out the task at hand with relative ease. Seeing that having supervision on location with extensive down hole experience and communication skills are helpful components to getting a directional well drilled properly and on target, this currently is the preferred system that is in place in the industry to directionally and horizontally drill wells.
Directional drillers use survey programs to monitor operations. Survey programs that are currently in use in the directional industry represent the well bore positioning as per a particular survey point (10 to 16 meters behind the bit positioning or hole depth) in the well bore, and it is up to the directional driller on location to factor in all the well and well bore variables to make the correct decision as to any and all well deviation corrections that are needed to keep the well bore on the predetermined well trajectory in a time efficient manner. Due to this increase in specialized drilling activity it has created a tremendous shortage of qualified manpower in the directional drilling industry.
Remote Directional Drilling. A directional subcontracting service company dispatches an individual to set up the survey equipment and down hole Bha at the beginning of the job. After ensuring that everything is operating properly the individual leaves location and the well trajectory is controlled by a text messaging relay system set up through the rig rat monitoring system, air card or in some cases a satellite phone system. The communication is based between the drilling contractor's driller on tower and a directional driller that is working out of a central command center off location that is monitoring the well.
Remote Directional Drilling does reduce some up-front costs of drilling the well by reducing a percentage of the man power expenses on location seeing that the directional driller that is monitoring the well trajectory monitors more than one well at a time from a central command center off location. However, the remote directional drilling system hinges on the assumption that the drilling contractor's driller on location is capable of steering the well with no assistance and in 90% of the situations this assumption has proven to be true. Thus, in some cases remote directional drilling has created added costs and risks to the drilling of directional and horizontal wells. In all cases of remote directional drilling the directional service company lowers its man power rates to the oil company so the oil company can realize a savings. This savings is at the expense of the experience of the directional drillers and the number of wells the directional driller is put in charge of monitoring. The driller does not have the advantage of knowing what is actually going on at location or any way of knowing if the instructions he relayed to the drilling contractor's driller are actually being carried out as instructed. Also because the well correction calculations are being performed off location the drilling contractor's driller on the other hand does not have the advantage of interacting with the directional driller and if he has any questions or issues he has to deal with them on his own. The drilling contractor's driller furthermore, has no idea of how the well is progressing (directional wise).
Not only does the drilling contractor's driller lose the advantage of interacting with the directional driller or knowing how the well is progressing, the oil company representative on location also loses this advantage and of course when the oil company representative on location loses communication pertaining to the progress of the well so does the oil company executives he is reporting too. In a lot of instances this missed communication and inexperience has sent the well trajectory off track to such a degree that the drilling operation has had to be halted and directional drillers dispatched to location to get the well back on track. In some of the extreme cases the well had to be cemented back in order to make the necessary well bore corrections. When remote directional drilling is used in a multi-well pad situation and it goes off track it not only puts the well that is being drilled in a critical situation, it puts one if not more of the wells on that same multi-well location in a critical situation or even can cancel out the drilling of some of the other wells on that same multi-well location. When this happens, the expense and cost to the oil company is astronomical.
Remote Supervised, Location Directional Drilling. This method of directional drilling is a combination of the previous mentioned approaches of directional drillers on location and remote directional drilling. Directional drillers are dispatched to location to supervise the directional aspects of drilling the well and relay the surveys and their planned directional corrections to an off location experienced directional supervisor working out of a central command center.
The off location remote supervising directional driller acts as a third directional driller for the well and is relied on to give the directional drillers on location a fresh perspective of the drilling of the well. The off location remote supervisor is actually a senior directional driller that is in control of the well and can assist, advise or overrule the directional drillers on location if he feels that the directional drillers on location are losing control of the well or making the wrong well correction decisions. The off location remote supervisor oversees and makes recommendations to the directional drillers on location, to the oil company representatives on location and in some cases to the oil company's drilling superintendent overseeing the drilling project. The off location supervisor also oversees well planning, Bha and bit changes and in some cases drilling parameters or drilling aspects depending on his experience.
However, such an approach is costly and has several major pit falls. Not only do the oil companies have to absorb the high cost of the directional drillers on location they also in some instances have the added costs associated with the remote directional drilling supervisor that is off location. This method of directional drilling is offered and sold to the oil companies on the premise that it will act as a safe guard to ensure that the predetermined well bore trajectory is maintained. However, this approach does nothing if the directional drillers are inexperienced. The remote directional drilling supervisor off location has the same issues to contend with as any other remote directional driller—he has no way of actually knowing what is going on, on location and has to rely on the directional drillers on location communication skills to keep him in the loop. Also, if the remote directional driller has never drilled in that particular area he can become a liability to the operation seeing that he actually has control over and can overrule the directional drillers on location.
Rotary Steerable System. Rotary Steerable Systems employ the use of specialized down hole equipment to replace conventional directional tools such as mud motors. Such systems are generally programmed by the MWD engineer or directional driller who transmits commands, using surface equipment, (typically using either pressure fluctuations in the mud column or variations in the drill string rotation) that the tool understands and gradually steers into the desired direction. In other words, a rotary steerable is a tool designed to drill directionally with continuous rotation from the surface, eliminating the need to slide to make well bore corrections or need of a mud motor. The methods used to direct the well path fall into two broad categories, these being push-the-bit or point-the-bit. Push-the-bit tools use pads on the outside of the tool which press against the well bore thereby causing the bit to press on the opposite side of the well bore causing a direction change. Point-the-bit technologies cause the direction of the bit to change relative to the rest of the tool.
Continuous rotation of the drill string allows for improved transportation of well bore cuttings to be carried, by the drilling fluids, to surface resulting in better hydraulic performance, better weight transfer for the same reason and reduced drill string torque. Therefore, the well bore can be less aggressive and smoother than those drilled with a mud motor using the fractured drilling method (slide and rotate) that is predominantly utilized by all other directional drilling systems.
The directional drillers or MWD operators that run the rotary steerable systems have to have down hole knowledge and experience as well as the ability to translate surveys into what well bore corrections have to be done to keep the predetermined well bore trajectory on track. As well they have to have sufficient computer experience and knowledge to be able to program the rotary steerable assembly to do what is needed to make the proper corrections without over or under steering the well bore. Because of the high level of technology that was put in the development of these systems and the high level of oil field experience, computer and down hole knowledge that is required to operate a rotary steerable system the day rate cost of these systems is astronomical compared to the conventional methods that are currently utilized by the oil and gas industry. In comparison to using a mud motor and a fractured steering system to keep the well bore on its predetermined trajectory a rotary steering system can cost upwards of $18K to $30K (or higher) per day in comparison to $8K to $12K per day for a mud motor. Directional Drilling Companies that provide rotary steerable systems sell them on the basis of drilling the same depth well in a shorter time frame, as per days needed to drill the well. However, it takes upwards of 20 minutes or more to program the down hole computer in the system after the operator gets the survey to make the needed corrections and this gets time consuming and costly for the oil company.

These tools use second inclination and gamma sensors in the bottom end of the Bha that are placed anywhere from ½ meter to 6 meters behind the bit vs. the normal distance of 10 to 16 meters. The near bit inclination and gamma tools are usually composed of two subs, making the inclination and gamma ray image sensors completely independent. The lower transceiver sub houses the sensor packages, batteries, and electronics which process the at bit gamma ray imaging along with inclination before they are transmitted through the drilling fluid and formation to the upper transceiver sub. The upper transceiver sub transfers the at bit measurements through the MWD tool for mud pulse telemetry to the surface. The lower and upper transmission subs act in conjunction as a repeater sub combination that transmit the near bit measurements to the surface.
Near Bit Inclination and Gamma improves survey inclination accuracy by eliminating the need to estimate the inclination at the bit by extrapolating the inclination based on the survey results, which could be 10 to 16 meters behind the bit or the hole depth. Both the near bit inclination and gamma at the bit enable the on location directional drillers and geologists to keep better control of the well bore and make any needed well bore trajectory corrections without having to factor in the unseen hole that has already been drilled that is ahead of the standard inclination and gamma sensors.
Near Bit Inclination and Gamma still requires directional drillers to be dispatched to location with down hole knowledge and experience and the ability to translate the surveys into what well bore corrections have to be done to keep the predetermined well bore trajectory on track. Near bit inclination and gamma subs can cost anywhere from an extra $3K to $5K a day and do nothing to speed up the drilling process. This equipment is highly technical and the oil and gas company representatives both on location and in the head offices have to entrust a major percentage of control of their wells to independent directional service companies that may or may not have the right personnel on location. If the directional service company dispatches personnel with poor communication skills the loss of control issue is only magnified exponentially.

Wire-Less Communication Data Base System #1: Referring to
The analysis and display module 42 may be configured to compare one or more characteristics of the orientation of portion 22 of drill string 14 with a well plan. A well plan is used to keep the drilling process on track and drill the well along the precise coordinates designated by the oil company. The well plan may be include a series of three dimensional points forming a path to the desired ultimate target, with intermediate points being interpolatable to provide a comparison of well progress at any point of drilling progress. By comparing progress of the well drilling with the well plan, a driller and all other interested parties can keep apprised of progress, correct any deviations from the well plan, and re-plan the well or plan a side track to deal with problems as they arise.
Other modules may be included such as an identification module 48 for confirming the identity of a user of the hierarchy of users as discussed further below. An alert module 46 may be provided for sending alerts as discussed in more detail below. A lock out module 49 may be provided for at least partially locking out one or more users from the system as discussed below.

Terminals may be actual physical terminals or virtual terminals such as a browser in an oil company executive's office. One or more remote terminals may be used, such as terminals 1h, at least one of which may be at a headquarters of an oil company as shown. To increase the amount of control the oil company has over the drilling, the hierarchy of users may comprise an oil and gas company representative at or near the top of the hierarchy of users.
Server 34 may include a conflict module 38 for determining if a conflict exists between a command received from a first user, such as directional driller 1d, of a hierarchy of users and a previous command from a relatively higher ranked user of the hierarchy of users, such as an individual 1h at a head quarters of an oil company. A conflict is found for example if a user tries to do something that a relatively higher ranked user has prohibited or flagged for supervisory approval. The previous command may thus include a standing order on the system 32, for example a parameter set up during the startup phase of the system 32 before the well is drilled. Server 34 may also include an execution module 40 for executing the command if no conflict exists. The execution module may represent one or more modules, such as analysis and display module 42, that actually implement the user's command if permitted, by for example calculating drilling instructions or processing survey results, and outputting data to a display. The hierarchical model discussed in this document provides the oil companies executives, supervisors and representatives on and off the location with the ability to take total and absolute control over all the well parameters and regulate decisions relating to the directional aspects of the well bore. Such control is possible despite the delegation of the drilling task to individuals who may or may not be under direct operational control by the oil company.

Active Code Screen #7:
The operator that is in control of the well may create and enter their own private acceptance code to take and maintain absolute control of the well parameters and to regulate any decisions relating to any and all directional aspects of the well bore. The preceding acceptance code activated always over-rides any acceptance codes below it, in other words the oil company representative on location or oil company representative monitoring the well from the head office can automatically take control of the well at any given point in the well if their instructions are not being carried out to their expectations. The Active Acceptance Code may have to be coded in (activated) to incorporate any well targeting coordinate changes, well section window coordinate changes, well plan changes, well plan acceptance, well sidetrack planning, well sidetrack acceptance, well section corridor warnings and alarms (window corridor parameters), and to deviate from drilling instructions proposed by the system 32.
The hierarchy coding system enables the operator with higher authority to over-ride any other acceptance code no matter where they are in the acceptance code order and is the only acceptance code that can authorize or initiate certain changes such as changes to the well bore trajectory when needed. Currently the hierarchy of the oil company executives relies solely on the experience of the on location supervisors they hire or contract to monitor, interpret and communicate any well bore issues to the head office and entrust that the service companies (directional) they sub-contract dispatch qualified personnel to drill their wells. Thus, oil companies are at the mercy of the on location personnel to get their wells drilled in an effective and efficient manner, however anyone that is skilled in the industry art knows that most of the on location supervisors the oil companies hires or contracts to supervise their wells do not have the technical experience or knowledge to recognize when a well is going of track until it is too late due to the fact that technology and methodology behind drilling these well bores in the oil and gas industry is continually changing at an alarming rate. The sub-contracting directional service companies cannot keep up with the demand for properly experienced trained personnel due to the great demand for directional personnel in the oil and gas industry, consequently the directional service companies are attempting to fill the void by turning to inexperienced oil field rig personnel. This inexperienced rig personnel is rushed through directional training and is expected to direct and assist the drilling contractor's driller, however they lack any type of practical rig experience and prove to be no assistance to the rig personnel.
The proceeding acceptance code activated may always over-ride acceptance codes below it, in other words if the oil company representative on location or oil company executive off location monitoring the well from the head office can automatically take control of the well at any given point in the well if their instructions are not being carried out to their expectations.
By tracking all change commands, enter survey commands, and other user input the system provides increased accountability for the plurality of users who interact with the system. In some cases the system tracks and records any and all Bha changes, target coordinate edits, section window corridor parameter edits, survey window corridor percentages, section window corridor parameter breaches, personnel changes, active acceptance coding, well bore calculations, slide/rotate initiations, and motor/Bha outputs. Referring to
For every new survey that is entered the system may calculate and record and displays on the program header page the meters, feet, degree or percentage the drilled well bore is moving off the pre-determined planned well bore trajectory based on the inclination, Tvd (true vertical depth), azimuth, plan view line, and motor/Bha output. For every new survey that is entered the system may calculate and record and display on the program header page the percentage the drilled well bore is moving off the pre-determined planned well bore trajectory based on the inclination, Tvd (true vertical depth), azimuth, plan view line, and motor/Bha output.
In some cases, the previous command that may or may not conflict with a user's subsequent command is to send an alert to one or more superiors in the hierarchy of users in the event of a predetermined type of command from the first user. Thus, for certain or all change commands, an alert may be sent to a supervisor or supervisor or all users. In some cases, approval of the command may be required before further operations take place. In other cases the user may be disallowed from making those type of changes altogether, and the command may be thus blocked. Thus, the precise level of delegation and hands-off or hands-on control may be exerted upon the drilling staff as desired by the oil company.

Predetermined Well Coordinates & Preset Windows #8:
Windows may be used to keep the well on track. Thus, in one case the analysis and display module 42 is configured to determine if a breach has occurred as indicated by a deviation, beyond a predetermined window, of a characteristic from a respective expected characteristic from the well plan. The alert module 46 may do one or more of initiate an alert event or send an alert to one or more of the users of the hierarchy of users in the event of a predetermined condition like a window breach. Deviations may be found as follows. A plurality of characteristics of the orientation of the portion of the drill string in the earth is measured, for example directly by input by a user of a survey result into the system 32, or indirectly by calculation from other directly entered data. Measuring may thus comprise one or more of measuring with a survey sensor or processing, with the one or more computing units, survey sensor data. The portion 22 of the drill string measured may comprise a drill bit for example if calculations are made to extrapolate survey data to the bit. For each measured characteristic, the one or more computing units determine if a breach has occurred as indicated by a deviation, beyond the predetermined window, of the measured characteristic from a respective expected characteristic from a well plan. If one or more breaches are determined an alert may be sent to one or more or all of the users of the system 32.
In some cases the predetermined condition warranting alert includes breaches across successive iterations of survey data input for a) the same characteristic or b) different characteristics. Thus, if an operator red lines (deviates beyond the predetermined window) inclination for two back to back surveys, the alert is sent. Other events may occur as a result of the predetermined condition being realized, including lockout of the user from further use of the interface. In other cases the predetermined condition includes completion of a portion of a well, such as completion of the build portion 30 (
The predetermined condition may include, at least partially locking out, with the one or more computing units, one or more users from repeating the measuring or determining stages, for example until clearance is received from a supervisor in the hierarchy. Thus, if the system 32 records two successive breaches, the driller may be locked out from entering further survey data and using the system to assist in drilling. Any further drilling will be done blind, so the lock out feature is an effective tool to prevent a well from going too far off course to correct. Such a warning system gives the oil company or anyone involved in drilling the well an early warning or a percentage (%) of progress relating to the predetermined well bore trajectory as the well is being drilled. Safe-Guard Warning System (phase #1): The system 32 red line safe-guard warning system is set up in a two stage process when one predetermined well bore parameter is breached a single warning will be sent to everyone on and off location monitoring the well performance allowing the operator on location to evaluate and correct the issue at hand. Safe-Guard Warning System (phase #2): When related red line warnings are received in two back to back surveys or two related predetermined parameter red lines are received within the same survey the system 32 program may prompt the operator to re-plan and re-evaluate the well trajectory by locking out the operator from entering any new surveys and send out a continuous warning signal to all personnel both on and off location that are monitoring the well performance until all personnel acknowledge that the second red line warning was received.
As indicated the warning system may also encompass drilling warnings as targets are reached or about to be automatically changed out, as well section targets are being reached, as lower than normal motor/bha outputs calculated prompting the operator to check for formation changes, when any window parameter corridor is getting close to being breached or is breached and what percentage of window parameter corridor that is deviated from.
The expected characteristics may be derived by the one or more computing units from the well plan based on a length of drill string inserted into the earth. Thus, if 2000 m of drill string has been inserted, the system 32 determines the expected characteristics, such as TVD, inclination, and azimuth, from the well plan expected at 2000 m of inserted pipe. Because the well plan may consist of discrete data points the expected characteristics may need to be interpolated between well plan points. Using such a method and monitoring components like inclination, azimuth, and at least one three dimensional coordinate of portion 22 such as TVD, allows an operator and all users monitoring the drilling to identify problems before such problems result in large physical deviations from the well plan. For example, deviations from a well plan often start with a deviation from the inclination or azimuth, and if uncorrected over several surveys may result in a large TVD deviation. Otherwise, if a user merely monitors the three dimensional position of the portion 22, such as the absolute distance from the well plan path, a user can only detect deviations after the fact, and possibly when it is too late to correct the well without re-planning. Motor output efficiency may also be monitored by windows, as discussed below. The three dimensional coordinates may include the position of the portion of the drill string projected in a horizontal plane, also referred to as the plan line view. Plan line view is often obtained by summing the horizontal plane coordinate changes between surveys. Plan line view is useful for determining if the well is out to the left or right of the well plan projected in the horizontal plane. Each characteristic can be graphed to illustrate deviations (

Predetermined Well Coordinates & Preset Windows, Windows Percentage (%) Parameters #8h: In some cases determining a breach as discussed throughout this document may further comprises assigning a grade associated with major, minor, or no deviation, in which a breach corresponds to a major deviation. The grades, such as percentage points shown in the percentage scaling portion of
When any of the section window corridor parameters are breached the system records and displays which parameter(s) was breached and at what level on the program header and in the survey file based on a green, yellow or red breach coding this enables the operator to instantly assess the well bore positioning and what corrections need to be done. The color coding is displayed in the survey file by color coding each survey depth a parameter was breached and color codes the parameter that is displayed in the survey file that was breached such as the inclination, Tvd, azimuth, or motor/Bha output. The program header also displays the well bore positioning and color codes each parameter based on Tvd (above/below, meters or feet), inclination (ahead/behind), plan view line (right/left), azimuth (ahead/behind) and vertical section (ahead/behind); this color coding is also assigned and displayed by the well bore positioning in every one of the parameters listed above as per the percentage (%) of the window percentage (%) parameter the well bore positioning is out or moving out.
Predetermined Well Coordinates & Preset Windows, Automatic or Manual Window Parameter Build Section Close #8i: The method may be carried out through a build section of the directional drilling operation, and may further comprise repeating the stages. Referring to
The windows close parameter is the automatic default setting and closes at a rate of 50% of the preset window corridor parameters for every 50% of the Build Section drilled and automatically stops a 0.25 of a meter or 0.82 of a foot. The leave as manual function command has to be activated and accepted through the active acceptance code in order for the operator to override the automatic close window corridor function. If the leave as manual function is activated and accepted it is recorded in a viewable, but un-editable worksheet. The close window corridor automatic function channels the well bore trajectory to the center of the landing point well coordinate for the build section. This function does not allow the well bore trajectory to over or under shoot the intended landing coordinates. This function tightens the corridor gradually as the build section is being drill to insure a proper smooth well bore is drilled on target in every instance.
The calculation is based on the Tvd and plan view line adjusted and derived from the pre-set pre-determined active well bore plan that is being used to drill the well. That is if the build section is 300 meters in length from the kick off point to the landing or casing point and the window parameter corridor is set at 3 meters (2 meters above and one meter below) for every 50% of the build section drilled the window corridor will automatically close at a rate of 50%. In other words at 150 meters of the build section being drilled the window corridor will close to 0.50 of a meter below and 1.0 meter above; then again at 225 meters of the well bore being drilled (that is 50% of 300 meters, then 50% of the remaining 150 meters of the build section which is 75 meters equaling 225 meters of the build section drilled) the window parameter corridor will close once again to 0.25 of a meter below and 0.50 of a meter above; the once again at 262.50 meters of the build section drilled the window parameter corridor will close to 0.13 of a meter below and 0.025 of a meter above; then once again at 281.25 meters of the build section the last window corridor will close to 0.07 of a meter below and 0.13 of a meter above to achieve the minimum window corridor of a total of 0.20 of a meter, then the system will automatically adjust the window corridor to 0.25 of a meter in total (splitting the difference equally).
As the system is closing the Tvd window corridor it will be duplicating the exact same function for the plan view line. Other characteristics may be closed in addition to or instead of TVD and plan view line. At 300 meters of build section the plan view window corridor is automatically set at 2 meters right and 2 meters left of the plan view line based on the pre-set pre-determined active well plan. At 150 meters of the build section being drilled the plan view window corridor will close to 1 meter right and 1 meter left; at 225 meters of the build section being drilled the plan view window corridor will close to 0.50 of a meter right and 0.50 of a meter left; then at 262.50 meters drilled in the build section the plan view window corridor will close to 0.25 of a meter right and 0.25 of a meter left; The at 281.25 meters of the build section being drilled the window corridor will close for the last time to 0.125 of a meter right and 0.125 of a meter left for a total close of the window parameter corridor of 0.25 of a meter.

Data Sheet Layover #19:
Referring to
As the well bore is drilled the calculations are done to hit the dead center of the target 62 coordinates. However, as the operator closes in on a target within a distance such as 10 meter or 32.8 feet the calculations may become skewed because if the well bore is in the window parameter corridor but is a little high or low (right or left) the calculations will still be based on the target dead center that well bore corrections are being calculated against, but because of the close proximity of the well bore target coordinates the well bore correction calculations will be attempting to hit the dead center of the target coordinates that in essence has already been achieved. The system 32 recognizes the target coordinate measured depth and as the well bore that is being drilled and gets within 10 meters or 32.8 feet of the target's measured depth at which point the system will automatically drop the close proximity target coordinates and automatically start to calculate the well bore corrections against the next target 64 in line in the same section. This function of automatic target change works on a section by section basis. Thus, the system reads every target and drops and move to each target in each individual section that is being drilled the vertical/drill down, build section, or lateral section, the system will not jump from a build section target to a lateral section target until the command is activated telling the system that the lateral section is being drilled.

Slide, Rotate Control #23: In some cases the methods may include measuring the elapsed time of an event, such as drilling time, forming part of the directional drilling operation. The system 32 may output from the one or more computing units to a display the elapsed time or a measurement made using the elapsed time. Such a method makes it possible to calculate ROP in a passive survey monitoring system. Other events such as one or more of slide time, rotate time, tool face orientation time, and connection time may be measured. Such a system provides a real time system for tracking rate of penetration (ROP) for slides, rotates, lost tool faces, actual single drill time, or average connection time (aspects that are extremely important to directional drilling). After the data sheets automatically calculate what action has to be performed to either keep the well bore on track or the necessary well bore corrections the slide/rotate control automatically is activated and as the operator activates each command Orient, Slide, Rotate, Lost Tool Face or End Single the system automatically times and times out and records each individual operation in a viewable but non-editable worksheet. Because the system allows the operator to do this the operator can use this information to make decisions on bit selection vs. formations being drilled through.

Slide, Rotate Control, Lost Tool Face Command #23c: Reference element 23c depicts the Lost Tool Face Command, while the operator is performing the calculated well bore correction via sliding or steering the well bore and if the operator cannot properly control the tool face setting and is unable to maintain the calculated tool face setting he activates the lost tool face command for every time that the tool face setting is corrupted which automatically times out and records the slide command and times in and records the lost tool face command activation, as soon as the operator has the tool face re-set he re-activates the slide command and the system automatically times out and records the lost tool face command and re-activates and records the new slide command. The operator performs this series of activations until he gets control of the tool face orientation or setting by changing drilling parameters such as tool face, weight on bit, down hole pump pressure, down hole differential pressure etc. If this continually happens for every well bore correction the operator has to look at the possibility getting the drilling contractor's driller help or instruction, however if the drilling contractor's driller is skilled in the art he will have to look at possibly changing out some aspect of the bottom hole assembly configuration such as the bit or bit motor configuration etc.

(Rise as Negative (−) Number/Distance) Acos. Drop the operator enters the meters/feet wanted or needed to drop as a positive (+) number. (Drop as Positive (+) Number/Distance) Acos. Distance the operator enters the meters/feet the rise or drop will be done in. Inclination the inclination is automatically calculated that will be need at the bit extrapolation based on the rise or drop and the distance entered.
b. Sub Sea or Tvd Change at a Given Inclination. Extrapolated Bit Inclination (Inc.) the operator enters the extrapolated bit inclination. Distance the operator enters the distance (m/ft) that is intended to drill at that given inclination. Rise the rise is automatically calculated based on the inclination and distance entered. The operator is locked out of this cell. (Cos Inclination)×Distance, The rise will calculate out as a negative (−) number. Drop the drop is automatically calculated based on the inclination and distance entered. The operator is locked out of this cell. (Cos Inclination)×Distance, The drop will calculate as a positive (+) number.
When the operator activates the Tvd/Inc. Calculator Command and enters the necessary data either in part a or b this will enable him to make a well informed decision as to what will be needed to move the well bore to achieve the necessary well bore corrections. If the operator has to move the well bore up or down as per meters or feet in the lateral section the operator uses part (a) of the Tvd/Inc. Calculator; if the operator has to calculate how much the well bore will drop or rise at a given angle over a set distance he uses part (b) of the Tvd/Inc. Calculator.
When and operator uses part (a) of the Tvd/Inc. Calculator he will know what angle he will need to achieve and maintain, at the bit, to move the well bore up or down a given number of meters or feet over a given distance. If the calculated angle is too high or too low the operator can either adjust the given distance the well bore has to be moved up or down in or the overall distance that the movement will be adjusted in. This calculation enables the operator to make an informed decision which enables him to better control the well bore trajectory as not to jeopardize the well bore integrity.
When the operator uses part (b) of the Tvd/Inc. Calculator he will know what distance the well bore will drop or rise at a given angle over a given distance. If the calculated drop or rise is to aggressive or to gradual the operator can either adjust the angle or the overall distance in which the adjustment is being made in. This calculation enables the operator to make an informed decision which enables him to better control the well bore trajectory as not to jeopardize the well bore integrity.

Motor/Bha Output #46:
In some cases the motor output efficiency may also be monitored by windows. Thus, throughout a build section 30 of the directional drilling operation, the plurality of characteristics measured may include one or more of an achieved dog leg or build rate of mud motor 17. Computing units 34 may then determine if a breach has occurred as indicated by a deviation, beyond a predetermined window, of one or both of the achieved dog leg or build rate from a respective expected dog leg or build rate of the mud motor. Motor output efficiency or percentage is a useful characteristic to monitor because it is often the first indication of a problem that could eventually lead to a sizable absolute distance deviation from the well bore plan path. The Motor/Bha Output percentage (%) is used to identify if the down hole assembly is achieving above or below the motor settings theoretical dogleg output. If the motor/bha output percentage is lower than 100% this means that the formation or the manner in which the slides are being carried out is not enabling the motor or Bha to achieve its theoretical potential and will put the well bore in jeopardy if nothing is changed. The bottom hole assembly may even have to be pulled out of the hole to change out the type of bit of dial up the motor (increase the motor angle setting). If the motor/bha output is higher than 100% of the theoretical motor or Bha output this means the operator can cut back on the meters or feet that are being slid to achieve the well bore corrections that are needed as not to over steer the well. The motor/bha output percentage is actually the first warning signal that something is not going to plan and major problems will follow if things continue as they are. After motor output efficiency, inclination, azimuth, TVD and then line rank in order from most sensitive to least sensitive indicators of problems with the drilling.
