  • Patent number: 8684086
    Abstract: A downhole mixing tool and method for removing sand and other debris from a wellbore which combines the sand with a treatment fluid so that the sand is lifted to the surface of the well for removal. The tool includes a chamber into which the sand laden fluid is drawn and the treatment fluid is introduced. Ports into the chamber are arranged to provide a pressure drop to draw the sand laden fluid into the chamber and a mixing time within the chamber before sand laden fluid of lower viscosity exits the chamber to travel to the surface. Additional features include blades on the tool for breaking up obstructions prior to being drawn into the chamber and a lubricating line through the tool to introduce lubricating fluid to the blades.

  • Patent number: 8256505
    Abstract: A well cellar system includes a substantially planar base plate, the base defining an aperture sized to receive a conductor pipe. The planar base plate is an integral structural member which, in conjunction with the seal between the base plate and the wall and the riser and the conductor, are sufficiently robust to support the weight of the conductor pipe and its auxiliary equipment. The sealed well cellar is afforded with a laterally extending flange which serves as an anti-buoyancy anchor. A anti-buoyancy port allows the upward floatation pressure to be balanced out by water pressure within the cellar during placement to avoid floatation. A sacrificial anode housing is provided with a removable lid and holes for allowing passage of electrolyte. Although the preferred embodiments of sealed well cellars are metal and plastic, a cementaceous embodiment is also envisioned.

  • Patent number: 7472745
    Abstract: A flow sensor is incorporated into a junk basket to sense a flow stoppage due to a plugged screen or plugged cuttings ports in a mill. The sensor triggers a signal to the surface to warn personnel that a problem exists before the equipment is damaged. The sensor signal to the surface can take a variety of forms including mud pulses, a detectable pressure buildup at the surface, electromagnetic energy, electrical signal on hard wire or radio signals in a wifi system to name a few options. Surface personnel can interrupt the signal to take corrective action that generally involves pulling out of the hole or reverse circulating to try to clear the screen or mill cuttings inlets. Other variables can be measured such as the volume or weight or rate of change of either and a signal can be sent to the surface corresponding to one of those variables to allow them to be detected at the surface in near real time.

    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: 6196319
    Abstract: An apparatus and method for removing sand and other debris from a wellbore. The apparatus is particularly suited for wireline operation, and requires minimal surface equipment. A housing is lowered into the wellbore until the housing is proximate to the sand, and a valve is opened to permit entry of the sand into a housing chamber. The housing can be raised to the wellbore surface so that the sand can be removed from the housing chamber. In one embodiment of the invention, the housing has two chambers each having a floating piston. A liquid is initially retained within the first chamber and is pressurized as the housing is lowered into the wellbore. Activation of a valve and differential pressures acting across the first piston move the liquid into the second chamber and draw the sand into the first chamber. The second chamber captures the liquid and facilitates return of the pistons to the initial position after the sand is emptied from the first chamber.

    Abstract: A nipple is provided downhole as part of a tubing (drill string or production) string. The nipple has an interior passage with recesses therein and a seat. A data probe attached to a wireline traverses inside of the tubing from the surface to the nipple.

A first latch deploys into a recess in the nipple to retain the probe in place against the formation pressure. A bypass is provided so as to equalize pressure across the data probe, when the probe is to be released. The bypass is kept closed by a second latch that deploys into another nipple recess. When the probe is to be retrieved to the surface, the bypass is opened by unlatching the second latch, thereby allowing pressure to equalize. The probe is unseated by unlatching the first latch. The probe has instrumentation and a sampling chamber which can be brought to the surface during flow periods of a test.

  • Patent number: 5058669
    Abstract: An elastic rebound pump comprises a flexible inner tube having a substantial elastic rebound surrounded by a pump housing. The inner tube defines an inner chamber and the pump housing forms an outer chamber for confining a pump fluid. The pump allows pressurized gas or hydraulic fluid into the outer chamber to collapse the inner tube thereby discharging liquid from the inner chamber through an outlet opening. The pump alternatively releases the pressurized fluid from the outer chamber thereby allowing the inner tube to rebound to a full configuration and draw liquid into the inner chamber through the inlet opening. By repeatedly allowing pump fluid into the outer chamber and sequentially releasing the pump fluid from the outer chamber, the pump produces a substantially steady flow of liquid. An extraction pump system includes the elastic rebound pump for removing liquid hydrocarbons from ground water collected in a well.
