  • Patent number: 8820402
    Abstract: A shock absorbing system has a nose assembly that is formed to inwardly collapse on impact and is guided by a sleeve that can slide with the nose as the nose collapses or can extend for a portion of the length of the nose while being held fixed. In the latter instance the nose can have a leading end that has a biasing member in a resilient material so that on impact some of the shock is taken up by compression of the biasing member with subsequent extension of the biasing member retracting the resilient covering so that it is less likely to bind in the surrounding tubular. The leading end of the sleeve or the resilient material encasing the biasing member also soften the blow to a closed ball when the tool is dropped so that the ball surface is less likely to mar.

  • Patent number: 8225859
    Abstract: A debris cleanup tool uses a movable eductor to reconfigure the flow scheme through the tool. During the debris pickup mode, pressurized fluid is delivered to through the tubing to the eductor inlet. The outlet of the eductor is into the surrounding annulus where the flow splits with most going to the surface and the rest down and into a mill making cuttings. The flow into the mill takes the cuttings to a collection volume and then screens the internal flow stream before directing it into the eductor inlet. The eductor body can be repositioned to close the eductor outlet to the annulus and open the outlet into the housing to allow reverse flow. In one embodiment a ball is dropped and pressure is built to break a shear pin to shift the eductor body and to open a bypass around the ball.

  • Patent number: 7779907
    Abstract: A downhole shock absorber preferably is filled with well fluid in a chamber that is reduced in volume due to impact. A rupture disc can hold the initial non-compressible liquid charge until impact. Upon impact, the rupture disc breaks to allow the fluid to be forced through an orifice to absorb some of the shock that occurs when a string hits a fixed object after dropping in the wellbore. The nose of the shock absorber is a soft material that has voids so that the combination of the softness of the material and the voids allow the nose to reshape until it encounters a surrounding tubular wall and then to collapse inwardly into the voids, making it simple to remove. The nose is releasably mounted to the shock absorber so the two can separate if the nose gets stuck after impact.

  • Patent number: 7281584
    Abstract: A downhole apparatus such as multi-cycle circulating subs used during downhole drilling operations includes a piston (42) slidably mounted in a body (4) between positions in which at least one aperture (40) in the body is opened and closed. Movement of the piston (42) is controlled by a pin (86) secured to one of the body and a control member, and a control groove (52) in which a portion of the pin is received formed in the other of the body and control member. An arrangement of elements (32,76) respectively connected to the control member and body is such that, as the control member moves axially, increasing lengths of the elements locate adjacent one another so as to provide resistance to relative rotation in at least one direction of the control member and body. The relative rotation is rotation which presses the control member against the control groove. The risk of damage to the control pin is thereby reduced.

  • Patent number: 7073590
    Abstract: A bi-directional seal assembly can be used in various types of cartridge valves including dirty fluid valves and a variety of other valves. The present seal assembly utilizes a seal spool, two O-rings and opposing seal cups. Back-up rings are provided to engage the O-rings to control deformation of the O-rings. The O-rings are compressed during manufacture of the seal assembly and the valve more than typically recommended by O-ring manufacturers. Because of this compression, the O-rings serve a dual function. At lower pressures, the O-rings act as a spring causing the seal cups to contact the opposing seal plates and at higher pressures they act as seals between the seal assembly and the valve.

  • Patent number: 6907926
    Abstract: A system is provided for unloading accumulated liquids and enhancing the recovery of gas from a reservoir having diminished pressure. An annulus between a tubing string and casing is isolated by a packer and continually pressurized with a slipstream of compressed gas while the well continues to produce. A unique valve positioned in the tubing string is shuttled between a production position in which production fluids are permitted to bypass the valve to the surface and a lift position in which the bypass is blocked and an unloading port is opened to vent high pressure annulus gas to the tubing string above the valve, lifting accumulated liquids with it. Preferably, the valve is actuated to the lift position by the impact of a plunger dropped from a lubricator at the wellhead, when the pressure in the annulus has reached a predetermined threshold.

  • Patent number: 6907797
    Abstract: A tank contains both Zeolite and a hydrate in a gas chamber formed beneath a piston in the sample tank. Out of safety considerations, we avoid using source cylinders of nitrogen whose pressures exceed 4000 psi. Thus, the gas chamber of the sample tank is initially pressurized by the source cylinder to no more than 4000 psi of nitrogen at room temperature at the surface. Nitrogen gas is sorbed onto the zeolite at room temperature. As the tank is heated by being lowered downhole, nitrogen desorbs from the zeolite and the gas pressure increases. However, once this tank reaches a temperature high enough to release the hydrate's water of hydration, the released water is preferentially sorbed by zeolite, displacing sorbed nitrogen, and causing the pressure in the gas volume to increase even further. Because well temperatures are not high enough to desorb water from zeolite, any water sorbed onto a Zeolite sorption site will permanently block released nitrogen from resorbing at that site.

  • Patent number: 6851473
    Abstract: For extracting a liquid (such as oil) from a porous medium, the liquid is subjected to pulses that propagate through the liquid flowing through the pores of the medium. The pulses cause momentary surges in the velocity of the liquid, which keeps the pores open. The pulses can be generated in the production well, or in a separate excitation well. If the pulses travel with the liquid, the velocity of travel of the liquid through the pores can be increased. The solid matrix is kept stationary, and the pulses move through the liquid. The pulses in the liquid can be generated directly in the liquid, or indirectly in the liquid via a localized area of the solid matrix.
