Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 4301

US Classification:

166335, 166105, 166106

Abstract:

A riser is installed which extends from a wellhead near the sea floor to near sea level. An electrical submersible pump assembly is suspended within the riser to pump well fluids up the riser. The electrical submersible pump includes impellers for displacing well fluids, and a base member having an intake port for receiving well fluid. The pump assembly can also include a separator for separating any gases from the well fluids, a packer for sealing the pump to the riser, coiled tubing from the pump to at least the upper end of the riser, or NPSH stages to aid in pumping a mixed flow of well fluids and gas.

Abstract:

Methods for staged production from a wellbore include pumps sequentially operated during the life of the well. In described embodiments, production assemblies are used for progressive staged production process in which the production tubing is bifurcated to provide a pair of legs. One of the legs includes a first pump that may be selectively actuated to flow fluid through one of the legs. Means are also provided, including a sliding sleeve and a flapper valve diverter, for blocking production fluid flow through one leg or the other. A second fluid pump is lowered inside of the production tubing to pump fluid after the first pump has failed.

Abstract:

âWell equipment transporting well fluid from a gassy well. A conduit is hung and sealed inside a string of casing, forcing the gas and well fluid to flow into the conduit. A gas separator and a series of flow controls and valves are mounted into and run with the conduit. A pump assembly is hung and sealed into the conduit for pumping well fluid to the surface. The pump assembly is lowered and retrieved from the conduit on tubing. The pump may be located below the motor, or above the motor. â.

International Classification:

E21B 2912

US Classification:

166366, 357105, 357335

Abstract:

A system for producing hydrocarbon fluids from a subsea formation includes at least one producing well penetrating the formation for producing hydrocarbon fluids. At least one dummy well is hydraulically connected to the at least one producing well for routing the hydrocarbon fluids from the producing well to the dummy well. At least one pump is disposed in the at least one dummy well. The pump takes suction flow from the dummy well and boosts the flow energy of the discharge flow of hydrocarbon fluids.

E21B 43/01

US Classification:

166304, 166335, 166368

Abstract:

A system monitors and controls the injection of additives into formation fluids recovered through a subsea well. The system includes a chemical injection unit and a controller positioned at a remote subsea location. The injection unit uses a pump to supply one or more selected additives from a subsea and/or remote supply unit. The controller operates the pump to control the additive flow rate based on signals provided by sensors measuring a parameter of interest. A one mode system includes a surface facility for supporting the subsea chemical injection and monitoring activities. In one embodiment, the surface facility is an offshore rig that provides power and has a chemical supply that provides additives to one or more injection units. In another embodiment, the surface facility includes a relatively stationary buoy and a mobile service vessel. When needed, the service vessel transfers additives to the chemical injection units via the buoy.

Abstract:

A seafloor pump assembly is installed within a caisson that has an upper end for receiving a flow of fluid containing gas and liquid. The pump assembly is enclosed within a shroud that has an upper end that seals around the pump assembly and a lower end that is below the motor and is open. An eduction tube has an upper end above the shroud within the upper portion of the caisson and a lower end in fluid communication with an interior portion of the shroud. The eduction tube causes gas that separates from the liquid and collects in the upper portion of the caisson to be drawn into the pump and mixed with the liquid as the liquid is being pumped.

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 4314

US Classification:

1661055

Abstract:

The present invention related to a system which prevent coning while minimizing the problems associated with any reverse coning which may result. The system includes a production string disposed within a wellbore having both oil production perforations and water production perforations, wherein the production tubing is packed off against the wellbore annulus between the oil production perforations and the water production perforations. In addition to a pump for producing oil from the oil production perforations, a water pump is incorporated into the production tubing proximate the water production perforations in order to pump water to a reinjection point or other location. The system also permits recovery of amounts of oil and even solids existing within the water layer, preferably by the use of a separator. The separated oil is then directed upward through the production string for recovery. The invention permits increased pump rates by the pumps located both above and below the packer.

International Classification:

E21B 4340

US Classification:

16625001

Abstract:

A computerized (e. g. intelligent) downhole oil/water separation system. A hydrocyclone separator is used downhole to separate oil from water. Downhole sensors monitor parameters associated with the oil/water separation and provide signals representing the parameters to a controller. The controller controls operation of the system by generating control signals and providing the control signals to one or more control devices. The oil/water separation is optimized and well profitability is enhanced.
