Patent number: 10480304Abstract: Downhole drilling vibration analysis uses an angular rate sensor on a drilling assembly. During drilling operations, the sensor measures the angular rate of the drilling assembly. Processing circuitry is operatively coupled to the angular rate sensor and is configured to determine whether torsional type vibrations are occurring during drilling based on the angular rate data. Drilling operations can then be modified to overcome or mitigate the torsional type vibrations.Type: GrantFiled: October 12, 2012Date of Patent: November 19, 2019Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Charles Lee Mauldin, Roger P. Bartel, Richard Berns

Method and apparatus for communicating incremental depth and/or other useful data of a downhole tool
Patent number: 10100630Abstract: A method and apparatus for communicating incremental depth and/or other useful data of a downhole tool. The incremental depth and/or other useful data of the downhole tool being communicated by measuring at least one change in the downhole system, detecting the change downhole, and subsequently determining the incremental depth and/or other useful data of the downhole tool.Type: GrantFiled: February 12, 2015Date of Patent: October 16, 2018Assignee: Weatherford Technology Holdings, LLCInventors: Roger P.

Patent number: 8881844Abstract: Disclosed herein is a system for steering the direction of a borehole advanced by cutting action of a rotary drill bit by periodically varying action of a drill bit while continuously rotating a drill string to which the drill bit is operationally attached. The steering system can include a bit perturbation device cooperating with a bent housing subsection and operationally connected to the drill string and to the drill bit. Drill bit action can be varied by periodically varying the rotation speed and/or rate of penetration of the drill bit. Periodic drill bit action results in preferential cutting of material from a predetermined arc of the borehole wall which, in turn, results in borehole deviation. Action of the drill bit can be varied independently of the rotation rate of the drill string.Type: GrantFiled: September 14, 2011Date of Patent: November 11, 2014Assignee: Precision Energy Services, Inc.Inventors: Steven Reid Farley, Michael Louis Larronde, Roger P. Bartel, Charles Lee Mauldin, Robert Anthony Aiello

Patent number: 8417456Abstract: Downhole drilling vibration analysis uses acceleration data measured in three orthogonal axes downhole while drilling to determine whether drilling assembly's efficiency has fallen to a point where the assembly needs to be pulled. In real or near real time, a downhole tool calculates impulse in at least one direction using the measured acceleration data over an acquisition period and determines whether the calculated impulse exceeds a predetermined acceleration threshold for the acquisition period. If the impulse exceeds the threshold, the tool pulses the impulse data to the surface where the calculated impulse is correlated to efficiency of the assembly as the drillstring is used to drill in real time. Based on the correlation, operators can determine whether to pull the assembly if excessive impulse occurs continuously over a predetermined penetration depth.Type: GrantFiled: July 27, 2012Date of Patent: April 9, 2013Assignee: Precision Energy Services, Inc.Inventors: Charles Lee Mauldin, Barry Vincent Schneider, Mark Adrian Smith
