Patent number: 8447523Abstract: A system for determining at least one of a lithology of a formation traversed by a borehole and an operational condition of a component of a drill string disposed in the borehole is disclosed. The system includes a drill string with a high speed wired pipe telemetry system for transmitting downhole measurements made by a sensor to a computer processing system in real time. The computer processing system is external to the drill string and includes a model that models operation of the drill string and/or a formation that is being drilled. The model receives the downhole measurements and surface measurements of a drilling parameter and provides as output detection of the lithology of the formation and/or the operational condition of the component.Type: GrantFiled: August 15, 2008Date of Patent: May 21, 2013Assignee: Baker Hughes IncorporatedInventors: Hanno Reckmann, Pushkar N.

Patent number: 6769497Abstract: Determination of the rate of penetration (ROP) of drilling has usually been based upon surface measurements and may not be an accurate representation of the actual ROP. This can cause problems in Logging While Drilling (LWD). Because of the lack of a high-speed surface-to-downhole communication while drilling, a conventional method of measuring ROP at the surface does not provide a solution to this problem. However, the instantaneous ROP can be derived downhole with a certain degree of accuracy by utilizing an accelerometer placed in (or near) the tool to measure acceleration in the axial direction. When three-component accelerometers are used, the method may be used to determine the true vertical depth of the borehole.Type: GrantFiled: June 11, 2002Date of Patent: August 3, 2004Assignee: Baker Hughes IncorporatedInventors: Vladimir Dubinsky, Pushkar N. Jogi, James V. Leggett, III, Douglas J. Patterson, Alexei Bolshakov, Volker Krueger

Patent number: 6142228Abstract: The operating speed of a rotor in a progressive-cavity Moineau-type pump is determined on a real-time basis using frequency analysis of vibration or pressure data to ultimately compute the rotor speed. Vibration and pressure or bending moment and axial acceleration data can be used to compute the rotor rotational frequencies. A high-amplitude peak in the frequency domain in any of the data sets which corresponds to the motor whirl frequency given by .omega..sub.m N.sub.r, where .omega..sub.m represents the motor frequency in radians per second and N.sub.r represents the number of lobes in the rotor, can be isolated. The motor rpm therefore equals .omega..sub.m /2.pi..60. In addition, modulated frequency peaks such as N.sub.r (.omega..sub.m +n.omega..sub.s) and N.sub.r (.omega..sub.m -n.omega..sub.s), where the modulating frequency is the pump stroke frequency .omega..sub.s, can also be observed.Type: GrantFiled: September 9, 1998Date of Patent: November 7, 2000Assignee: Baker Hughes IncorporatedInventors: Pushkar N.

Patent number: 5415030Abstract: A method for evaluating formations and bit conditions is presented. The present invention processes signals indicative of downhole weight on bit (WOB), downhole torque (TOR), rate of penetration (ROP) and bit rotations (RPM), while taking into account bit geometry to provide a plurality of well logs and to optimize the drilling process. Drilling operations are monitored and adjusted in response to these processed signals and logs. The processed signals may include the following signals: drilling response, differential pressure, pore pressure, porosity, porosity compensated for formation effects, drilling alert, bit wear factor, abnormal torque, and bearing wear. The logs may include a drilling response log, a differential pressure log, a porosity log, a porosity log compensated for formation effects, a drilling alert log, a wear factor log, a torque analysis log and a bearing wear log.Type: GrantFiled: April 8, 1994Date of Patent: May 16, 1995Assignee: Baker Hughes IncorporatedInventors: Pushkar N.

Patent number: 5141060Abstract: A method is presented for designing a bottomhole assembly whose tendency to build/drop or hold angle is independent of borehole inclination. This method comprises the adjustment of the location of any one of the first three stabilizers of an arbitrarily selected bottomhole assembly while the location of the remaining stabilizers is left in position. In accordance with the present invention, at one particular location of the stabilizer which has been selected to be moved, the resulting build/drop or hold rate of the bottomhole assembly is independent of borehole inclination.Type: GrantFiled: November 1, 1989Date of Patent: August 25, 1992Assignee: Teleco Oilfield Services Inc.Inventor: Pushkar N.
