摘要： Apparatus and methods pertaining to a moveable well construction apparatus to be electrically energized via an electrical power transmission path extending between a stationary power source and the moveable well construction apparatus. The path comprises cables and connectors. A system comprises a detector operable for generating information indicative of whether the path is properly installed. The system permits the path to be electrically energized when the detector-generated information indicates the path is properly installed, and prevents the path from being electrically energized when the detector-generated information indicates the path is not properly installed.

摘要： A method for reducing noise at a wellsite includes transmitting a plurality of first signals from a variable frequency drive (VFD) to an alternating current (AC) induction motor. A timing of a plurality of second signals is varied to control transistors in an inverter of the VFD, thereby reducing harmonic distortion of the first signals output from the VFD. The timing is varied based at least partially upon an estimation of the harmonic distortion.

摘要： A process for directional operations in a well bore without MWD, the process comprising: engaging an upper end of a drill string with a traveling block component, wherein the traveling block component comprises a traveling block angular sensor; measuring with the traveling block angular sensor an initial angular position of the drill string; lowering the drill string in the well bore with the traveling block component; measuring with the traveling block angular sensor a final angular position of the drill string; recording an angle of rotation, if any, of the drill string between initial and final positions as measured by the traveling block angular sensor; engaging the drill string with a rig floor component, wherein the rig floor component comprises a rig floor angular sensor; measuring with the rig floor angular sensor an initial angular position of the drill string; disengaging the traveling block component from the drill string; raising the traveling block component; engaging an upper end of a first tubular with the traveling block component; joining a bottom end of the first tubular to the drill string; measuring with the rig floor angular sensor a final angular position of the drill string; and recording an angle of rotation, if any, of the drill string that occurred between initial and final positions as measured by the rig floor angular sensor.

摘要： Pipes, drill strings including pipes, and methods for use on a drilling rig. The method includes obtaining pipe data for individual drill pipes of a drill string, obtaining a well trajectory for a well, obtaining one or more drilling measurements to be used when drilling the well, planning a first drill string based on the pipe data, the well trajectory, and the one or more drilling measurements, predicting an aging of the individual drill pipes in the first drill string while drilling the well using the first drill string, determining that a risk of failure of one or more individual pipes in the first drill string is unacceptable based on the aging of the individual pipes; and planning a second drill string in response to determining that the risk of failure is unacceptable in the first drill string.

摘要： A system for measuring rheological characteristics for drilling muds without the use of a delicate, expensive, or labor-intensive viscometer is disclosed. The system includes a fluid diverter circuit which retrieves a sample of the drilling mud and stores it in a reservoir where the pressure and level of the drilling mud are measured. The reservoir drains through a measurement pipe which enables a calculation of a flow rate. With the dimensions of the measurement pipe, the pressure, and the flow rate, a rheological chart can be assembled. The system can iteratively measure pressure and from the iterative data achieve a non-Newtonian factor, n′, confirm entrance length of the measurement pipe, and confirm that the flow in the measurement pipe is laminar.

摘要： A system for determining a location of a drill pipe joint deployed in a bore includes at least one magnetometer deployed on the bore. A processor is in electronic communication with the magnetometer and is configured to process magnetic field measurements made by the magnetometer to determine at least one of an axial position and a lateral position of the drill pipe joint.

摘要： A rig positioning system includes a first position system having a first component that is coupled to a movable drilling rig so as to be movable therewith. The first position system detects a position of the movable drilling rig on a pad with respect to a well. The first position system has a first accuracy. A second position system has a first component coupled to the movable drilling rig so as to be movable therewith, and a second component. The movable drilling rig is movable with respect to the second component. The second position system determines the position of the movable drilling rig with respect to the well. The second position system has a second accuracy that is finer than the first accuracy.

摘要： A method for transmitting data from a downhole tool to a surface location includes measuring a property in a wellbore using a downhole tool in the wellbore. A casing is positioned within the wellbore, and the downhole tool is positioned below at least a portion of the casing. A digital frame is generated using the downhole tool. The digital frame includes information corresponding to the property. The digital frame is encoded to superpose the information on a carrier signal. The carrier signal is converted to a voltage differential that is generated across an insulation layer in the downhole tool. The voltage differential causes a current to flow through a subterranean formation and into the casing above the downhole tool. A magnetic flux generated by the current flowing through the casing is detected using a sensor that is positioned at least partially within or at least partially around the casing.
