A radial bearing may include an annular sleeve sized and shaped to surround the head. A shaft washer may be sized and shaped to surround the head between an enlarged head of the tensioner bolt and the annular sleeve. A bearing element may be configured for positioning proximate the head, the bearing element comprising an upper surface configured for sliding, frictional contact with a lower surface of the shaft washer.

Abstract: A float collar tool for running a casing string assembly into a wellbore includes a non-fragmenting rupture disc that temporarily isolates light fluid trapped in a lower portion of the casing string from heavier fluid in the upper portion of the casing string, thereby reducing the horizontal weight of the casing string by an amount sufficient to overcome a drag force. After the casing string is landed at a final location in the wellbore, the rupture disc is burst by increasing fluid pressure in the upper portion of the casing string. The increased pressure activates a piston that then moves the burst rupture disc into a protective region of the tool so that the inside diameter of the casing string is substantially restored.

Abstract: A gas-separator for separating trapped gases from drilling fluids retrieved from a well-bore being drilled is disclosed. The gas-separator includes a barrel separator which rotates on its longitudinal axis when pressurized drilling fluid flows out through its fluid ejection ports. Ejection of fluids from the fluid ejection ports induces rotation of the barrel separator which helps separate gases from the fluid. After separation, the gases travel out from the upper sub and to the surface, up the well-bore. The treated and gas-cleansed fluid travels downstream to the drill string and any downstream equipment, including pumps, motors, and drill bits, or; treated and gas-cleansed fluid may flow to the surface directly after treatment in the gas-separator.

The apparatus further includes a plurality of slip arms located around the outer surface of the retaining body, each slip arm extending between top and bottom ends and having an inner surface extending from the top end corresponding to the outer surface of the retaining body and an exterior surface adapted to frictionally engage a wellbore; and a seal element located around the outer surface of the retaining body above the plurality of slip arms adapted to be displaced towards the top end of the retaining body by the plurality of slip arms so as to seal an annulus between the retaining body and the wellbore.

Abstract: A circulation sub including a tubular and a diverter valve are configured to continuously circulate fluid into a drill string. The tubular has a first end connectable to the drill string, a second end connectable to a pipe segment, and a port. The tubular has a fluid path for allowing the fluid to flow from the pipe segment to the drill string and a circulation path for allowing the fluid to flow from the port to the drill string. The diverter valve has a channel in selective fluid communication with the fluid path. The diverter valve is positionable between a flow through position for selectively allowing the fluid to flow through the fluid path and a diversion position for selectively allowing the fluid to flow through the circulation path whereby the fluid may continuously flow through the drill string.

Abstract: A method for operating a pressure operated device in a wellbore includes conducting pressurized gas to a power fluid inlet port of a valve at a first pressure. The first pressure is selected to cause a shuttle in the valve to be positioned to enable flow of the pressurized gas through the valve to a power fluid flow port in communication with a power fluid inlet of the pneumatic device. Pressure of the pressurized gas is increased to a second pressure greater than the first pressure, whereby the shuttle moves to close the power fluid inlet port to flow and to vent the power fluid flow port to ambient pressure in the wellbore.

Abstract: A bottom hole actuator tool for locating and actuating one or more sleeve valves spaced along a completion string. A shifting tool includes radially extending dogs at ends of radially controllable, and circumferentially spaced support arms.

Abstract: The present invention is directed towards an apparatus for providing a nonlabor-intensive process for sealing an opening formed in the ground with a chemically-inflatable bag. The chemically-inflatable bag contains two or more chemical reactants, one of which is a liquid reactant that is initially stored in a liquid-containing device. The liquid-containing device has a removable cap, which upon removal or breakage of the cap permits the liquid reacting agent to contact and react with another reacting agent. The chemical reaction produces carbon dioxide, which expands the chemically-inflatable bag from a collapsed condition to an inflated condition. In the inflated condition, the chemically-inflatable bag fills and protects the integrity of the formed cavity.
