Abstract: The present invention is directed to methods for an off-site supervisor or well owner to evaluate the rig load data provided by a well service rig at a well site by evaluating charts of sensor data obtained from sensors on or associated with the well service rig. A rig load data chart can be reviewed and activities completed by the rig identified based on the data curves on the rig load data chart. In addition the hook load carried by the service rig can be determined by evaluating the rig load data charts of sensor data. Furthermore, well bore and tubing conditions in the well can be analyzed based on the rig load data in the rig load data charts while tubing and rods are being pulled from the well or well bore.

Abstract: An operator of a well service rig can retrieve and monitor a display of data on the position of a block during rod and tubing insertion and removal. The operator inputs into the system a minimum and maximum height range that he wants the block to operate within. Data is provided to the operator, in real-time, on a charted display relative to the maximum and minimum position input by the operator to assist the operator in evaluating the position of the block prior to a crown-out or floor-out. In addition methods are provided for evaluating the activities conducted by a rig based on evaluation of the block position data in order to supervise a rig operation from an off-site site location. Furthermore, the technology allows the operator or supervisor to determine the speed of the block during operations by evaluating encoder velocity data provided by an encoder velocity chart.

Abstract: A target pressure value is determined during the learning mode. Subsequent pressure values are then compared to the target value. For example, a first connection is tightened in a conventional manner, while its pressure is monitored during the learning mode. If the tightening process went well, then an operator pushes a button that tells the monitor to remember how much pressure was used on the tongs to tighten the first connection. The pressure value of that first joint then becomes the target pressure value for any subsequent joints. As additional joints are tightened, the pressure applied to the tongs is monitored and compared to the first one to ensure that all the joints are as good as the first one within an allowable tolerance.

Abstract: The present invention is directed to methods of evaluating the operations of a well service rig at a well site by evaluating charts of sensor data obtained from sensors on or associated with the well service rig. An activity listing or Gantt chart can be reviewed and each activity verified by viewing charts of sensor data obtained during that purported activity. In addition service rig downtimes can be determined and evaluated through the evaluation of charts of sensor data. Furthermore, activities and completion times for each activity can be determined by evaluating charts of sensor data obtained from sensors on the service rig or at the well site to verify the operations of the service rig, to improve the efficiency of the operators by identifying long activities and providing additional instruction, and provide improved billing to customers by correcting activities and the time associated therewith.

Abstract: The brake system includes a brake lever independent of, but capable of rotating about the same point as a bell crank. Upon receiving a downward force, a member extending from the lever strikes a portion of the bell crank and generates a force that cause the bell crank to rotate. Rotational action of the bell crank transfers rotational energy to an equalizer bar thorough a linkage system. The equalizer bar's rotation increases or decreases tension on brake bands that slow a tubing drum. A cylinder can activate and cause the equalizer bar to rotate, applying tension to the brake bands and slowing the drum. Rotational energy is transferred back to the bell crank through the linkage. The rotational energy is absorbed by a spring positioned between the bell crank and the brake lever, thereby reducing the amount of sudden force passed through the brake lever to an operator.

Abstract: The present invention provides an automatic system for engaging the hydromatic brake on a drilling rig or a service rig. This system monitors both the hook load and traveling block velocity, and uses an electrical solenoid to activates the hydromatic when either the hook load or rotating drum velocity exceeds a maximum value, requiring hydromatic brake engagement.

Abstract: This invention discloses a process which when properly used, automates the hydrostatic testing of casing and/or tubing in a will. An electronic processor with programmable logic provides diagnostics, alarming, and process automation functionality to the process. Current downhole tools and pumps can be used to insure conformance to API specifications, however the processor would sense that a specified target pressure has been reached and start an internal clock. After a specified period of time, the pressure would again be analyzed and compared to the original start pressure. If the decline is within specified limits, one alarm is given and recorded. If the decline in pressure is above the limits, another type alarm could he displayed, heard, and recorded. A PLC can also be incorporated to perform such tasks as starting the pump, closing and opening surface valves, and stopping the pump.

Abstract: Disclosed herein is a system designed to manage or slow the block travel speed down to safe speeds when the rig is operating in a light load/high speed condition. The system monitors and controls engine torque and horsepower, providing the minimum amount of each necessary to pull the light load out of the hold without providing sufficient excess torque to pull the load through a snag.

Abstract: The technology disclosed herein provides a multiple sensor system that prevents crown incursion by a traveling block in an oil rig. This system calculates traveling block position, traveling block velocity and weight supported by the traveling block, and uses this information to calculate emergency stopping positions to prevent crown out by the traveling block. The system takes all these parameters into consideration when slowing and/or stopping the traveling block when it reaches a crown out position. The result is much safer operation of the traveling block on a workover rig, as well as on an oil drilling rig.

Abstract: The present invention is directed to incrementing a well service rig in such a manner that activity-based and/or time-based data for the well site is recorded. The invention contemplates that the acquired data can be transmitted in near real-time or periodically via wired, wireless, satellite or physical transfer such as by memory module to a data center preferably controlled by the work-over rig owner, but alternately controlled by the well owner or another. The data can thereafter be used to provide the customer in various forms ranging from a detailed invoice to a searchable, secure web-based database. With such information, the customer can schedule other services at the well site. Further, the customer will have access to detailed data on the actual service performed and can.
