摘要： A bridge plug for use in a wellbore to isolate an upper portion of the wellbore from a lower portion. The bridge plug is run into the wellbore on wireline or run-in tubular and then set in the wellbore at a predetermined depth. In one aspect of the invention, the bridge plug includes a cylindrical body having a longitudinal bore therethrough which is sealed to the passage of fluid. A first and second lock ring assemblies are installed on the outer surface of the body and are designed to move in a single direction with respect to the body. A bidirectional slip member which provides resistance to axial forces in two directions and a sealing member is located on the exterior of the body. A sealing member is disposed between the first and second lock ring assemblies and is actuated by movement of the first ring towards the second ring.

摘要： A system and method is provided for converting a drilling rig between conventional hydrostatic pressure drilling and managed pressure drilling or underbalanced drilling using a docking station housing mounted on a marine riser or bell nipple. This docking station housing may be positioned above the surface of the water. When a removable rotating control device is remotely hydraulically latched with the docking station housing, the system and method allows for interactive lubrication and cooling of the rotating control device, as needed, along with a supply of fluid for use with active seals.

摘要： A rotating control device is remotely hydraulically latched and unlatched with a docking station housing for use and removal, respectively. The system and method allows for interactive lubrication and cooling of the rotating control device, as needed, along with a supply of fluid for use with an active seal. A first sensor and a second sensor can be used to detect temperature, pressure and density of the supplied fluid at different locations and this data can be compared using a central processing unit (CPU). Also, a sensor can be used to detect the revolutions per minute of a rotating seal of the rotating control device and fluid can be provided to the rotating control device responsive to the detected revolutions per minute.

摘要： A latch and method for use is provided for latching an item of oilfield equipment. The latch has a housing containing a latch member, and the latch member is movable between a radially engaged position in which it is engaged with the item of oilfield equipment, and a radially retracted position in which it is disengaged from the item of oilfield equipment. An actuator is configured to drive the latch member into the radially engaged position. Further, the actuator is configured to drive the latch member toward the radially retracted position.

摘要： A system and method is provided for a low profile rotating control device (LP-RCD) and its housing mounted on or integral with an annular blowout preventer seal, casing, or other housing. The LP-RCD and LP-RCD housing can fit within a limited space available on drilling rigs. An embodiment allows a LP-RCD to be removably disposed with a LP-RCD housing by rotating a bearing assembly rotating plate. A sealing element may be removably disposed with the LP-RCD bearing assembly by rotating a seal retainer ring. Alternatively, a sealing element may be removably disposed with the LP-RCD bearing assembly with a seal support member threadedly attached with the LP-RCD bearing assembly. The seal support member may be locked in position with a seal locking ring removably attached with threads with the LP-RCD bearing assembly over the seal support member. Spaced apart accumulators may be disposed radially outward of the bearings in the bearing assembly to provide self lubrication to the bearings.
