Patent number: 9657561Abstract: A dynamically controllable variable displacement axial piston pump is described. In an embodiment, the pump comprises a rotating cylinder with hydraulic pistons that contact the face of a swash plate. The angle of the swash plate can be controlled to thereby control the movement of the pistons, the displacement of the pump, and the power generated by the pump. The dynamically controllable variable displacement axial piston pump may be used in combination with a rotary steerable apparatus, including such an apparatus as described herein that uses hydraulic pistons to actuate the deflection of the bit, or in combination with other downhole tools and devices. When used down hole in a drill string with a drilling mud powered turbine, the dynamically controllable variable displacement pump limits and regulates the power provided to the tool over a wide range of drilling mud weights and flow rates.Type: GrantFiled: January 6, 2016Date of Patent: May 23, 2017Assignee: ISODRILL, INC.Inventors: Saad Bargach, Stephen D. Bonner, Raymond V. Nold, III, James P. Massey, Jon A. Brunetti

Patent number: 9650834Abstract: The rotary steerable drilling tool and system described herein combines both point-the-bit and push-the-bit techniques to actively change the direction of the borehole trajectory. In this system, the deflection of the drill bit is limited to a single degree of freedom relative to a coordinate system that is fixed to and rotates with the rotary steerable drilling tool, resulting in a simplified attachment of the bit assembly and bias unit mechanics. Further, steering of the well is accomplished by dynamically controlling the spatial phase and amplitude of the coherent symmetrical bidirectional reciprocating deflections of the drill bit relative to a fixed terrestrial datum as the tool is rotating, simultaneously pointing and pushing the bit.Type: GrantFiled: September 9, 2016Date of Patent: May 16, 2017Assignee: ISODRILL, LLCInventors: Saad Bargach, Stephen D. Bonner, Raymond V. Nold, III, James P. Massey, Jon A. Brunetti

Further, steering of the well is accomplished by dynamically controlling the spatial phase and amplitude of the coherent symmetrical bidirectional reciprocating deflections of the drill bit relative to a fixed terrestrial datum as the tool is rotating, simultaneously pointing and pushing the bit. The amplitude and force of the bit deflections can be variably controlled during steering operations to dynamically adjust the instantaneous build rate as needed. When steering is not active, the bit can be mechanically locked into the neutral position.Type: GrantFiled: January 6, 2016Date of Patent: October 11, 2016Assignee: ISODRILL, LLCInventors: Saad Bargach, Stephen D.

Patent number: 7458419Abstract: A probe assembly samples fluid from a wellbore penetrating a subsurface formation having a virgin fluid therein beyond a layer of contaminated fluid surrounding the wellbore. The probe assembly includes a probe body extendable from a downhole tool, and a packer carried by the probe body and having a distal surface adapted for sealingly engaging the wellbore. The packer has an outer and inner periphery, with the inner periphery being defined by a bore through the packer. The packer is further equipped with channel(s) formed in the distal surface and arranged to define an annular cleanup intake intermediate the inner and outer peripheries. The passageway(s) extend(s) through the packer for conducting virgin fluid and/or contaminated fluid between the channel(s). A sampling tube is sealingly disposed in the bore of the packer for conducting virgin fluid to a second inlet in the probe body and the downhole tool.Type: GrantFiled: October 7, 2004Date of Patent: December 2, 2008Assignee: Schlumberger Technology CorporationInventors: Raymond V.
