  • Patent number: 9765608
    Abstract: A lower separator located below a submersible well pump intake has a labyrinth flow path, causing a first well fluid separation of lighter components from heavier components as well fluid flowing into the lower separator turns downward to flow toward a lower separator heavier component port. A bypass riser has a bypass riser inlet below the pump intake and a bypass riser outlet above the pump intake. A lighter component conduit communicates the bypass riser inlet with lighter components of the first well fluid separation, causing a second well fluid separation at the riser outlet as a heavier portion of the lighter components flowing up the riser turn to flow downward to the pump intake. A heavier component conduit bypasses the bypass riser inlet and delivers the heavier components of the first well fluid separation to the pump intake.

  • Patent number: 9441435
    Abstract: A downhole apparatus comprising a body (12) configured to be coupled to a production tubular and an upper opening and a lower opening. First (28a) and second (28b) flow paths are provided between the upper opening (22) and the lower opening (24) in the body, and a flow diverter (34) is arranged to direct downward flow through the body towards the second flow path and away from the first flow path. A filter device (31) in the second flow path filters or collects solid particles in the second flow path from passing out of the lower opening of the apparatus. The apparatus has particular application to artificial lift hydrocarbon production systems, and may be installed above a down-hole pump in a production tubing to prevent solids from settling on the pump during pump shutdown. Embodiments for use with ESPs and PCPs are described.

  • Patent number: 8960282
    Abstract: A subterranean debris catcher takes in debris laden fluid at a lower end. The inlet flow is induced with an eductor whose discharge goes around the housing to the lower end inlet for the debris. The eductor suction induces flow into the lower end of the housing as well. Incoming debris goes up an annular space around the collection receptacle and turns to pass through a bladed wheel that imparts a spin to the flowing stream. The flow direction reverses from up before the wheel to down through a tube after the wheel. The solids are flung to the tube periphery and the fluid reverses direction to go back up to a screen before reaching the eductor suction connection. The debris swirls down an open bottom tube and is collected in a housing surrounding the down tube.

    Abstract: A method for determining wettability of a solid, such as a reservoir rock material, is described. The method includes disaggregating the material, for example by grinding and placing the disaggregated material on the surface of the fluid. The wettability is analyzed based on whether a portion of the material floats on or sinks into the fluid. The method is well suited for heterogeneous solid materials that have mixed wetting characteristics and/or have varying surface types. The fluid can be evaluated as a potential treatment fluid or a component thereof that can be used for treating the rock formation. For example, the potential treatment fluid can include a surfactant or an oxidizing agent. A simple observation can be made whether substantially all of the material placed on the surface of the fluid sinks into the fluid, or the portions of floating and sinking material can be weighed.

  • Patent number: 7748449
    Abstract: A method of producing a well utilizes a submersible pump run on a line, such as braided wire rope, that includes power conductors. The operator sets a packer in the casing, the packer having a check valve and a tieback receptacle. The operator pressure tests the integrity of the casing above the packer, and if it passes, then runs the pump assembly on the line. The pump assembly has a shroud with a downward extending extension that seals to the passage of the packer. If the pressure test of the casing fails, the operator runs a liner into the well and engages the tieback receptacle. A smaller diameter pump is then lowered on a line into the liner and into engagement with the packer.

    Abstract: A rod actuated downhole well pumping system is provided with spaced apart annular elastomer members secured to the pump rod at predetermined intervals to prevent solids particulates entrained in the pumped fluid from settling down to and clogging the pump mechanism during periods of pumping activity. The elastomer members are provided with longitudinal slits so that they may be sleeved over a pump rod without disconnecting the rod from the pump assembly in retrofitted installations. The elastomer members are preferably secured to the pump rod with a suitable adhesive and are of a diameter at least slightly less than the inner diameter of the tubing through which fluid is being pumped.

  • Publication number: 20080236834
    Abstract: An electrical wireline conveyed baling system for removing large volumes of liquids from a well borehole with a single trip of a bailer tool string. The system also utilizes one or more blow out preventers thereby allowing wireline bailing operations to be carried out while controlling well pressure. A bailer tool string that is conveyed by the wireline comprises a tool head containing a pump, at least one carrier section, and a no-return valve. Once deployed in the borehole, a first signal transmitted via the wireline from the surface activates the pump thereby reducing pressure within the carrier section. A second signal transmitted via the wireline from the surface opens the no-return valve thereby allowing liquid to flow from the borehole into the carrier section. The bailer tool string containing liquid is subsequently retrieved via the wireline thereby removing liquid from the borehole.

  • Patent number: 7219725
    Abstract: A plunger for use in a plunger lift system of an oil or natural gas well includes one or more sensor assemblies, each including one or more sensors for measuring various physical and operational conditions during the operation of the well. The data acquired from the sensors is stored in memory within the sensor assemblies and downloaded to the plunger lift system controller when the plunger is located in the catch/lubricator. The data can then be analyzed by the controller or other computer to vary the well's operating parameters to maximize the well's operating efficiency and the data can be used in reservoir management, such as transient testing, reservoir modeling and interference testing.

  • Patent number: 7150325
    Abstract: A subsea pumping assembly locates on a seafloor for pumping well fluid from subsea wells to the level. The pumping assembly has a tubular outer housing that is at least partially embedded in the seafloor. A tubular primary housing locates in the outer housing and has a lower end with a receptacle. An annular space surrounds the primary housing within the outer housing for delivering fluid to a receptacle at the lower end of the primary housing. A capsule is lowered in and retrieved from the primary housing. The capsule sealingly engages the receptacle for receiving well fluid from the annular space. A submersible pump is located inside the capsule. The pump has an intake that receives well fluid and a discharge that discharges the well fluid exterior of this capsule. The capsule has a valve in its inlet that when closed prevents leakage of well fluid from the capsule. The capsule may be retrieved through open sea without a riser.
