Publication number: 20240044212Abstract: A downhole drilling tool, forming part of a subterranean drilling system, may include at least one plate secured to an exterior of an elongate body. Electronics may be disposed between the plate and the body to be protected by the plate while still readily accessible. A dynamic element may be radially extendable from the plate to engage an inner wall of a borehole being drilled. If this radially-extendable element becomes worn or damaged from this engagement, the plate may be replaced. More expensive components of the drilling tool may be contained within the elongate body, rather than the plate, thus reducing replacement frequency. Additionally, plates including unique features may be employed at different times without altering the underlying elongate body.Type: ApplicationFiled: October 23, 2023Publication date: February 8, 2024Inventors: Jonathan D. Marshall, Steven G. Villareal, Michael George Azar, Scott Richard Woolston

Patent number: 11767723Abstract: A downhole transducer assembly capable of being safely operated at a variety of pressures and depths may include a turbine rotatable by a fluid pressure differential rotationally fixed to a rotor in a generator. To reduce the rotational speed of the turbine and rotor, a pressure regulator may limit a fluid pressure differential by controlling the volumetric flow. One or more nozzles may be configured to automatically regulate a nozzle diameter, and therefore the pressure drop across the nozzle. A surge protector may be connected to the generator.Type: GrantFiled: October 17, 2021Date of Patent: September 26, 2023Assignee: Schlumberger Technology CorporationInventors: Edward George Parkin, Scott Richard Woolston, Jonathan D. Marshall, David C. Hoyle, Jim Shumway

Publication number: 20230142360Abstract: A torsional damping system includes a housing having an interior space. An inertia ring is located in the interior space, and a torsion fluid is located between the inertia ring and the housing. The inertia ring is rotatably installed relative to the housing. As the housing oscillates, the inertia ring damps at least a portion of the oscillation. The torsional damping system may be included in a downhole tool or bottomhole assembly, and used to damp oscillations along a drill string or along the bottomhole assembly, including between a downhole motor and a cutting tool.Type: ApplicationFiled: March 30, 2021Publication date: May 11, 2023Inventors: Yuelin Shen, Mauro Caresta, Scott Richard Woolston, Clint William Philbrick

Publication number: 20230009998Abstract: A flow regulation system for downlink communication includes a fixed flow valve and a variable flow valve on a discharge line. A pressure sensor is located between the fixed flow valve and the variable flow valve. A sinusoidal communication flow pattern in the drilling fluid is generated by adjusting the position of the variable flow valve based on measured valve pressures from the pressure sensor.Type: ApplicationFiled: July 7, 2022Publication date: January 12, 2023Inventors: Milan Subotic, Scott Richard Woolston, Christopher Paul Reed, Pavel Annenkov

Patent number: 11542805Abstract: A downhole drilling apparatus, passing through a subterranean borehole, may mark an inner wall of the borehole with a marking element. A sensor, spaced axially from the marking element on the drilling apparatus, may subsequently sense the marking as it passes. A rate of penetration of the drilling apparatus may be calculated by dividing an axial distance, between the marking element and the sensor, by a time interval, between when the marking element marks the inner wall and when the marking is sensed by the sensor. Alternately, a second sensor, spaced axially from the first, may also sense the marking. A rate of penetration may then be calculated by dividing an axial distance, between the two sensors, by a time interval, between when the two sensors sense the marking.Type: GrantFiled: June 11, 2020Date of Patent: January 3, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jonathan D.

Publication number: 20210324726Abstract: A bit used in a downhole environment has an active element that is movable relative to the bit. The bit is rotated in the downhole environment, and at least one downhole parameter is measured. The at least one downhole parameter is compared against a target parameter value, and when the at least one downhole parameter is beyond a threshold value of the target parameter value, the active element is selectively relative to the bit. Movement of the active element alters the proportion of the weight on the active element as compared to the other cutting structure of the bit. Changing the proportion of weight can be used to reduce the depth of cut of the cutting structure and to reduce or eliminate motor stall or stick-slip behavior.Type: ApplicationFiled: August 27, 2019Publication date: October 21, 2021Inventors: Manoj D.

Patent number: 11015406Abstract: A sensor assembly may include a housing made of a non-magnetic material. The housing may define an interior chamber. A shaft may extend from the housing. A bearing may be positioned around the shaft. An impeller may be positioned around the shaft and the bearing, and the impeller may include a magnetized portion. A sensor may be positioned within the interior chamber and/or proximate the magnetized portion. The sensor may detect the magnetized portion of the impeller to sense a rate of rotation of the impeller. The rate of rotation of the impeller may correspond to changes in flow rate of the fluid. As the flow rate of the fluid, and the rate of rotation of the impeller change in predetermined manners, control signals may be conveyed to activate a tool.Type: GrantFiled: January 22, 2019Date of Patent: May 25, 2021Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jacques Orban, R.
