Abstract: A torque measuring vise, including a body for operatively supporting one or more movable clamping members defining a clamping axis for releasably securing an object; one or more sensors disposed about the torque measuring vise; and an electronic circuit in communication with the one or more sensors for producing one or more load responsive measurements.

Abstract: A downhole oilfield tool assembly comprises a mandrel, a ball valve oriented to block downwards flow through the mandrel in a closed position, a first piston located above the ball valve and at least partly around an outside of the mandrel. The first piston is configured to develop motive force from a pressure differential between an interior of the mandrel and an exterior of the downhole oilfield tool assembly.

Abstract: A tie back assembly and method of use is presented. In one method, a tie back seal mandrel is inserted into a tie back receptacle. Both the inner surface of the tie back receptacle and the outer surface of the seal mandrel are tapered to cooperate when mated. A seal assembly forms an annular seal between the tapered surfaces when the mandrel is inserted into the receptacle. Preferably the seal assembly has a burst seal and a collapse seal carried on one of the tapered surfaces, where the seals are spaced apart longitudinally. The seals are positioned at locations along the tapered surfaces to provide adequate wall thickness for support at pressure. Hydrostatic fluid in the wellbore increases the force necessary to withdraw the seal mandrel dues to creation of a lower pressure zone between the spaced apart seals.

Abstract: This application is directed to a pressure balanced mud motor. The mud motor includes a power section to rotate a passageway housing and propel fluid through a passageway disposed in the passageway housing. The mud motor also includes a hydraulic apparatus for balancing a pressure drop experienced across a bearing assembly due to frictional flow of fluid through the passageway.

Abstract: A downhole setting tool comprises a tool housing and a hollow mandrel, the mandrel being situated in the housing. The tool further comprises a piston situated between the mandrel and the tool housing and a collar situated between the mandrel and the tool housing, wherein the tool housing, the mandrel, the piston and the collar define an annulus. The tool further comprises a first valve, wherein in a closed position the first valve blocks a path of fluid communication between the interior of the mandrel and the annulus.

Abstract: A method for fracturing a wellbore in a formation, including positioning one or more bidirectional rotary sleeves on tubular members into the wellbore; engaging a unidirectional rotary source in a first position with a first bidirectional rotary sleeve of the one or more bidirectional rotary sleeves; operating the unidirectional rotary source to rotate the first bidirectional rotary sleeve in a first rotational direction to open at least one port in the first bidirectional rotary sleeve for providing an open fluid pathway between the first bidirectional rotary sleeve and the formation; pumping fluid through the tubular members and through the opened port to fracture the formation; engaging the unidirectional rotary source in a second position with the first bidirectional rotary sleeve; and operating the unidirectional rotary source to rotate first bidirectional rotary sleeve in a second rotational direction to close the at least one port in the first bidirectional rotary sleeve.
