Appl. No.:

09/685752

Inventors:

Wesley P. Dietz - Carrollton TX

Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

F16K 3102

US Classification:

25112913, 25112915, 464 30

Abstract:

A fail safe valve actuator is disclosed that is powered by an electric motor which drives through a wrap spring clutch and a centrifugal brake configured to absorb a portion of the energy released when the power fails and the valve stem is moved rapidly to its fail safe position by an actuator spring. The valve member is held in operating position by a solenoid. When power fails, a spring moves the valve stem in the other direction to move the valve member to its fail safe position. A torque limiting device is mounted adjacent the output end of a gear train to protect the gear train and the electric motor from the high torque created when the valve stem abruptly stops moving when the valve member reaches its operating position.

US Classification:

166 667, 166 53, 166 66, 166386, 1663328, 1663342

Abstract:

The present invention is a surface controlled subsurface safety valve (SCSSV) for use in a well, preferably a hydrocarbon producing well. The SCSSV comprises a valve body having a longitudinal bore for fluid to flow through, a bore closure assembly, a pressure balanced drive assembly, and a fail safe assembly. The bore closure assembly is positioned and normally biased to close the bore to fluid flow. The drive assembly is coupled to the bore closure assembly for driving the bore closure assembly to an open position. The fail safe assembly is positioned and configured to hold the bore closure assembly in the open position in response to a hold signal and to release the valve to return to the safe, closed position upon interruption of the hold signal.

US Classification:

175356

Abstract:

A rotary cone drill bit for forming a borehole having a one-piece bit body with a lower portion having a convex exterior surface and an upper portion adapted for connection to a drill string. The drill bit will generally rotate around a central axis of the bit body. A number of support arms are preferably attached to pockets formed in the bit body and depend therefrom. Each support arm has an inside surface with a spindle connected thereto and an outer surface. Each spindle projects generally downwardly and inwardly with respect to the longitudinal axis of the associated support arm and the central axis of the bit body. A number of cone cutter assemblies equal to the number of support arms are mounted respectively on each of the spindles. The spacing between each of the support arms along with their respective length and width dimensions are selected to enhance fluid flow between the cutter cone assemblies mounted on the respective support arms and the lower portion of the bit body. A lubricant reservoir is preferably provided in each support arm to supply lubricant to one or more bearing assemblies disposed between each cutter cone assembly and its associated spindle.

International Classification:

E21B 23/01

Abstract:

Provided, in one aspect, is an anchoring subassembly, a well system, and a method. The anchoring subassembly, in one aspect, includes a mandrel, and an isolation element positioned about the mandrel, the isolation element configured to move between a radially retracted state, a fully radially expanded state, and a relaxed radially expanded state. The anchoring subassembly, in one aspect, further includes a ratch latch body coupled to the isolation element, the ratch latch body configured to hold the isolation element in the fully radially expanded state, and a relief feature coupled to the ratch latch body, the relief feature configured to shear to release stored energy in the isolation element and thereby allow the isolation element to move from the fully radially expanded state to the relaxed radially expanded state.

International Classification:

E21B 41/00
E21B 23/00

Abstract:

A well system having primary and secondary wellbores wherein a completion sleeve is positioned in the primary wellbore and defines a window aligned with a primary wellbore casing exit and upper and lower couplings defined on opposing axial ends of the window. An isolation sleeve is positioned within the completion sleeve and defines a helical slot. The isolation sleeve is movable between a first position, where a engagement device engages the upper coupling and the isolation sleeve occludes the window, and a second position, where the isolation sleeve is moved axially within completion sleeve to expose the window and the engagement device engages the lower coupling. A whipstock assembly includes a latch key that selectively locates and engages an inner profile of the isolation sleeve to move the isolation sleeve to the second position. An orienting key mates with the helical slot to angularly orient the whipstock assembly.
