An arrangement of spatially separated sensors acquire pressure-responsive measurements at multiple positions within the plumbing of a drill rig. A receiver collects and digitizes the measurements from the spatially separated sensors and subjects them to a principal components analysis (PCA) to determine those one or more basis vectors associated the telemetry signal. The PCA process may employ decomposition of a spatial correlation/covariance matrix or a temporal-spatial correlation/covariance tensor. The selected basis vector(s) are then used to obtain the telemetry signal for demodulation into the telemetry data stream.Type: GrantFiled: August 16, 2013Date of Patent: January 8, 2019Assignee: Halliburton Energy Services, Inc.Inventor: Victor J.

Patent number: 10094210Abstract: Rock strength is estimated during drilling using a rate of penetration model or a modified mechanical specific energy models. The rock strength estimate can be used in conducting further drilling, for example by a drilling system. Drilling parameters may be altered as a result of determining rock strength, for example to avoid undesirable trending fractures, such as extensive vertical fractures.Type: GrantFiled: October 1, 2013Date of Patent: October 9, 2018Assignee: Rocsol Technologies Inc.Inventors: Geir Hareland, Mauricio Jose Farinas Moya, Prasad Baloo Kerkar, Ernesto Rafael Fonseca Ocampos

Patent number: 10012041Abstract: An apparatus and method automatically tally drill string rods for use with a drilling machine. The machine comprises a rack and a rotary drive configured for longitudinal displacement between first and second longitudinal positions. A sensor system is configured to monitor the machine to detect a clamping force applied to rotationally immobilize the drill string and to detect a break-out torque generated by the rotary drive, detect a first longitudinal position of the rotary drive whereat the break-out torque is generated, and detect a second longitudinal position of the rotary drive whereat a make-up torque is generated by the rotary drive. A controller is configured to prevent release of the clamping force until the make-up torque is detected, and automatically enable release of the clamping force after the make-up torque is detected and, concordantly, to update a drill rod tally only when the first and second longitudinal positions are different.Type: GrantFiled: July 24, 2017Date of Patent: July 3, 2018Assignee: Vermeer CorporationInventor: Philip R.

Method for measuring underground boring position and underground boring position measuring apparatus
Patent number: 9976410Abstract: The rotation angle around x axis, inclination angle and directional angle of a boring bit are obtained from the value measured with an accelerometer (22) and a three axis magnetic sensor integrally provided within the boring bit attached to the top of a rod array for boring. From these obtained values and the length corresponding to a rod, the amount of varied position according to boring by a length corresponding to a rod is obtained for each directional component. Further, the position of boring corresponding to boring in plural times with successive addition of rods is obtained through accumulating the amount of varied position for each directional component in respect of boring in plural times.Type: GrantFiled: January 23, 2015Date of Patent: May 22, 2018Assignees: KYUSHU UNIVERISITY, NATIONAL UNIVERSITY CORPORATION, YBM Co., Ltd.Inventors: Hideki Mizunaga, Toshiaki Tanaka -
Patent number: 9970237Abstract: A steerable earth boring assembly which includes an annular collar and a drive shaft with a drill bit, where the shaft pivots with respect to the collar. An upper portion of the shaft inserts into an orientation sleeve which resides in the collar. An axial bore is obliquely formed through the sleeve, and in which the upper portion inserts. Rotating the sleeve causes precession of the upper portion, thereby pivoting the drill bit obliquely to the collar. Selective rotation of the sleeve orients the drill bit into a designated orientation for forming a deviated wellbore. Included in the assembly is a flow tube with an end in sealing contact with the drive shaft.Type: GrantFiled: October 20, 2015Date of Patent: May 15, 2018Assignee: BITSWAVE INC.Inventors: Treston Greggory Davis, Ricki Don Marshall

Patent number: 9890592Abstract: A steerable earth boring assembly which includes an annular collar and a drive shaft with a drill bit, where the shaft pivots with respect to the collar. An upstream portion of the shaft inserts into an orientation sleeve which resides in the collar. An axial bore is obliquely formed through the sleeve, and in which the upstream portion inserts. Rotating the sleeve causes precession of the upstream portion, thereby pivoting the drill bit obliquely to the collar.

Patent number: 9784086Abstract: Disclosed is a method for extracting shale oil and gas by fracturing, and chemical retorting in oil shale in-situ horizontal well and a process for implementing the method. In the method and process, an inclined well is drilled from the ground to the upper part of an underground oil shale stratum, and a horizontal well is drilled in parallel to the oil shale stratum in the upper part of the oil shale stratum. Behind the horizontal well and the inclined well in the upper part, an inclined well leading to the lower part of the oil shale stratum is drilled, and a horizontal well is drilled in parallel to the lower part of the oil shale stratum. Highly pressurized media are injected into the horizontal well in the upper part of the oil shale stratum.Type: GrantFiled: May 4, 2014Date of Patent: October 10, 2017Assignees: Jilin Zhongcheng Oil Shale Investment and Development Co., Ltd.Inventor: Jinmin Zhao
