Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

E21B 4312

US Classification:

166373, 166 666, 1663321

Abstract:

Electrohydraulic actuators and associated methods are utilized to control the operation of downhole well tool assemblies, representatively flow control devices. In a described embodiment thereof, each actuator is positioned downhole and comprises a self-contained, closed circuit hydraulic system including an electrically operable double action primary pump drivingly coupled to an associated well tool assembly via a first hydraulic circuit, and an electrically operable switching pump coupled to the first hydraulic circuit via a second hydraulic circuit interposed therein and operative to selectively alter the control flow of hydraulic fluid to the well tool assembly in a manner reversing its operation. To provide for selective, more rapid control of the well tool assembly, a chargeable accumulator is connected to the hydraulic circuitry and is selectively and drivably communicatable with the well tool assembly.

International Classification:

E21B 404

US Classification:

166 665, 290 54, 31015601, 310267

Abstract:

A power generating system () for a downhole operation () having production tubing () in a wellbore () includes a magnetized rotation member () coupled to the wellbore () within the production tubing (), the rotation member () having a passageway () through which objects, such as tools, may be passed within the production tubing (). Support braces () couple the rotation member () to the production tubing () and allow the rotation member () to rotate within the production tubing (). Magnetic pickups () are predisposed about the rotation member () within the wellbore () and a power conditioner () is provided to receive currents from the magnetic pickups () for storage and future use. The rotation member () rotates due to the flow of fluid, such as crude oil, through the production tubing () which causes the rotation member () to rotate and induce a magnetic field on the magnetic pickups () such that electrical energy is transmitted to the power conditioner (), the power conditioner able to store, rectify, and deliver power to any one of several electronic components within the wellbore ().

International Classification:

E21B 43/12

US Classification:

166236, 166233, 166386, 1663321, 1663322

Abstract:

A fluid flow control device () for use in a wellbore to control the inflow of production fluids comprises a sand control screen () having a base pipe () with a first set of openings () that allows the production fluids to flow therethrough and a sleeve () coaxially disposed adjacent to the base pipe (). The sleeve () has a second set of openings () that allows the production fluids to flow therethrough. The sleeve () is selectively positionable relative to the base pipe () such that a pressure drop in the production fluids is selectively controllable by adjusting an alignment of the first set of openings () relative to the second set of openings ().

International Classification:

E21B 4/04

US Classification:

166 665, 290 54, 31015601, 310267

Abstract:

A downhole tool () for wellbore operations comprises a substantially tubular member () that is operably positionable in the wellbore and a rotation member () that is rotatably disposed within the substantially tubular member (). The rotation member () has a passageway () through which objects may pass into the wellbore. The rotation member () rotates about an axis of rotation (x) that is substantially perpendicular to the longitudinal axis (y) of the substantially tubular member () in response to fluid flow through the passageway (). The rotation member () has magnetic properties such that rotation of the rotation member () generates a magnetic field that produces useable power.
