Abstract: An apparatus for controlling flow of a fluid in a fluid conduit may include a closure member having an outer circumferential surface defined by a composite geometry, a biasing member applying a biasing force to the closure member, and a sealing member receiving the closure member. A fluid seal is formed in the fluid conduit when the biasing member presses the closure member against the sealing member.

Abstract: An anchoring system for use with a downhole tool includes a body with anchor members mounted on the body that pivot radially outward from the body and into engagement with an inner surface of a tubular. Curved slots are provided along a portion of the members and a sliding block has a protrusion that projects into the slots. The slots are curved so that when the block is urged axially within the body, the interaction between the slots and protrusions pivots the members radially outward. A piston is urged through the body to drive the block. Optionally, an elongate helical gear may cooperate with grooves formed in an edge of the members so that rotating the gear pivots the members radially outward.

Abstract: A well tool has a pressure sensor disposed in an interior space. The pressure sensor has at least one sensing element estimating a pressure parameter of a fluid in the interior space and a transponder configured to transmit radio frequency (RF) signals representative of the estimated pressure parameter. A data retrieval module receives the RF signals transmitted by the transmitter.

Abstract: A method of cutting a control line mounted on an outer surface of a downhole tubular that includes providing a cutting tool having a main body, and a cutting head on a lower end of the body that rotates with respect to the body. A cutting blade is on a lower end of the cutting head, which is rotatable by a motor, where the blade is selectively pivoted radially outward from an axis of the cutting head. As the cutting head rotates, the cutting blade orbits within the tubular axially offset from the axis. When the tool is inserted into the tubular, the radial offset of the blade is controlled so it pivots radially outward into contact with the tubular when the blade approaches an azimuthal area proximate the control line. The cutting blade is retracted when its orbit moves it past the azimuthal area proximate the control line.

Abstract: Devices and methods for cutting a workpiece. A cutter is provided with a fluid jet generator that creates and projects a jet of fluid proximate the cut being made in a workpiece.

Abstract: A wellbore tool includes a non-hydrocarbon-based grease disposed between a first component and a second component. The grease remains substantially impermeable to hydrocarbons at temperatures up to at least about 150° C. and possibly up to at least about 200° C., and pressures up to at least about 27 MPa and possibly to at least about 50 MPa. Methods of forming such wellbore tools include selecting a grease to comprise a non-hydrocarbon-based grease that remains at least substantially impermeable to hydrocarbons at temperatures up to at least about 150° C. and possibly up to at least about 200° C., and pressures up to at least about 27 MPa and possibly to at least about 50 MPa; and disposing the grease at an interface between a first component of a wellbore tool and a second component of a wellbore tool.

Abstract: In one aspect, an apparatus for drilling a wellbore into an earth formation is disclosed, which apparatus, according to one embodiment, may include a drill string configured to be conveyed into a wellbore, wherein an annulus is formed between the drill string and a wellbore wall, a first flow device configured to circulate a first fluid from an annulus to a bore of the drill string, and a second flow device positioned downhole of the first flow device, the second flow device configured to circulate a second fluid from the bore of the drill string to the annulus.

Abstract: A cutting tool that inserts into a tubular for cutting the tubular from within. The cutting tool includes a motor, a cutting head, permanent anchor between the motor and cutting head, an electronics portion, and a modular anchoring sub that can be between the motor and electronics portion or on the upper end of the cutting tool. The modular anchoring sub provides flexibility in where anchoring elements are positioned so that depending on the application, the modular anchoring sub can be positioned so that it provides its maximum anchoring force for stabilizing the cutting tool during use.

Abstract: The tubular cutting tool for severing downhole tubulars, the tool having a drive system, a pivoting system, a cutting head, a cutting member, and a lubricant delivery system. Cutting may be accomplished by rotatingly actuating the cutting head with an associated motor and extending the cutting member away from the cutting head. The lubricant delivery system lubricates the respective contacting surfaces of the cutting member and the tubular and is actuated when the cutting member extends from the cutting head.
