Filed:

Sep 1, 2004

Appl. No.:

10/931606

International Classification:

US Classification:

166377, 166378, 1663324, 166 667, 166105

Abstract:

A system and method for actuating a shut-off valve in a wellbore wherein the shut-off valve element can be positively closed before the pump is removed from the well. A hydraulic actuator component is operably associated with the shut-off valve to provide for selective isolation of the well by positive closing of the valve prior to removal of the pump and opening of the valve after replacement of a pump within the wellbore. The hydraulic actuator component has a balanced hydraulic design wherein the valve closure element may be moved toward an open or closed position by flow of hydraulic fluid through first and second hydraulic lines. When a repaired pump or replacement pump is placed into the well, the actuator is stabbed into a packer element to seat it. The hydraulic actuator assembly is then operated to open the shut-off valve, thereby reestablishing well operation.

US Classification:

166386, 1663321

Abstract:

Systems and methods for positively closing off a section of wellbore and, thereby providing reservoir control. Systems and methods are described for selectively closing off a section of a wellbore to fluid communication. The wellbore completion section may then be reopened to fluid communication upon reconnection of the upper completion section to the lower completion section. Advantageously, the systems and methods of the present invention generally preclude fluid communication between the annulus of the upper completion section and the flowbore of the lower completion section until the lower completion section is closed off to fluid flow.

US Classification:

175297, 175296

Abstract:

A hydraulic jar for a drilling assembly is disclosed. In some embodiments, the hydraulic jar includes a tubular housing, a mandrel disposed in the housing, an annulus between the mandrel and the housing, and a pressure relief mechanism disposed in the annulus. The pressure relief mechanism generally divides the annulus into first and second portions. The pressure relief mechanism includes first and second annular members in engagement with one another when the pressure in the second annulus portion is less than a predetermined value and a fluid flow path between the first and second annulus portions. The fluid flow path has a first size when the pressure in the second annulus portion is less than the predetermined value, and a second size that is larger than the first size when the pressure in the second annulus portion becomes equal to or greater than the predetermined value.

US Classification:

166/382000, 166/381000, 166/125000, 166/115000

Abstract:

A running tool that delivers an object selectively to one of a plurality of landing nipples and then releases from the object is disclosed. The tool is actuated by raising it after it has passed the desired landing nipple to release a locating dog. The locating dog places locking dogs on the object even with a groove on the landing nipple. Movement of the tool downhole secures the locking relationship and releases the running tool from the object. A sheer pin allows testing at the surface that the object is locked in place, prior to removal of the running tool. The object comprises a fishing neck to allow it to be subsequently retrieved.
