Of Advance Or Applied Tool Weight Patents (Class 175/27)
  • Patent number: 9784035
    Abstract: Apparatuses, methods, and systems are described which assist in controlling toolface orientation of a bottom hole assembly. A controller instructs a top drive to oscillate a drill string an oscillation revolution amount to reduce friction of the drill string in a wellbore during a slide drilling procedure. A torque sensor detects torque at an interface between the drill string and the top drive, and the controller determines properties of a torsional wave from the detected torque that is propagating along the drill string during the slide drilling procedure. The controller determines a modification to the oscillation revolution amount and/or rotations per minute in order to control the toolface orientation in a desired manner. The top drive implements the determined modification and thereby assists in controlling the toolface orientation during the slide drilling procedure.

  • Patent number: 8590635
    Abstract: A method for automated drilling of a borehole in a subsurface formation includes drilling the borehole using a set of drilling control variables assigned a set of values. An automated drilling index of the drilling is monitored. The automated drilling index of the drilling is a combination of a first index that depends on a rate of penetration of the drilling and a second index that depends on a mechanical specific energy of the drilling. The values assigned to the set of drilling control variables are selectively adjusted at least once during the drilling based on the monitoring of the automated drilling index.

  • Publication number: 20130277111
    Abstract: A method of automatically placing a drill bit used to form an opening in a subsurface formation on a bottom of the opening being formed comprises a) increasing a flow rate in a drill string to a target flow; b) controlling a flow rate of fluid into the drill string to be substantially the same as a flowrate of fluid out of the opening; c) allowing a fluid pressure to reach a relatively steady state; and d) automatically moving the drill bit toward the bottom of the opening at a selected rate of advance until an increase in measured differential pressure indicates that the drill bit is at the bottom of the opening.

  • Publication number: 20130146358
    Abstract: Processes and systems for drilling a borehole wherein a gravitational energy term, a torsional energy term, a hydraulic energy term and a hydromechanical specific energy which is the sum thereof may be determined using real-time data and compared against corresponding setpoints. The hydraulic energy term may include a hydraulic energy reduction factor so as to account for the distance between the fluid nozzle of the drill bit and the rock and may include the kinematic viscosity of drilling fluid. One or more drilling parameters, such as weight on bit, revolutions per minute, drilling fluid flow rate, or combinations thereof, may be adjusted based upon such comparison to approximate the least amount of energy required to destroy and remove a given unit volume of rock. The setpoints may be changed manually or automatically at the direction of the user.

  • Patent number: 8439129
    Abstract: An anti-stall tool in an oil well drilling assembly that controls reciprocation of the drill bit by a controller that alters weight-on-bit (WOB) depending upon measured downhole pressure or torque at the downhole motor. The controller receives preset high and low working pressure limits for the downhole motor and keeps the drill bit rotating by maintaining WOB during normal drilling operations, increasing WOB if sensed working pressure indicates that drill bit loading or torque is undesirably low, and reversing WOB by retracting the drill bit if excessive working pressure or torque is sensed.

  • Patent number: RE44956
    Abstract: A method and apparatus for precisely controlling the rotation of a drill string. A sensor monitors the rotation of the drill string and transmits the rotational information to a computer. The computer controls the rotation of the motor driving the drill string and rotates the drill string through an angle input by the operator. The computer may also utilize the sensor's rotational information to oscillate the drill string between two predetermined angles. The computer may also receive orientation information from a downhole tool sensor. The downhole tool information may be combined with the rotational information to enable the computer to accurately reorient the downhole tool.
