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.

摘要： Latch position indicator systems remotely determine whether a latch assembly is latched or unlatched. The latch assembly may be a single latch assembly or a dual latch assembly. An oilfield device may be positioned with the latch assembly. Non-contact (position), contact (on/off and/or position) and hydraulic (flowmeter), both direct and indirect, embodiments include fluid measurement systems, an electrical switch system, a mechanical valve system, and proximity sensor systems.
摘要翻译： 锁定位置指示器系统远程确定闩锁组件是否锁定或解锁。 闩锁组件可以是单个闩锁组件或双重闩锁组件。 油田装置可以与闩锁组件一起定位。 直接和间接的非接触（位置），接触（开/关和/或位置）和液压（流量计）都包括流体测量系统，电气开关系统，机械阀门系统和接近传感器系统。

摘要： A method and apparatus for retrieving an assembly having a whipstock and an anchor from a wellbore. A method of retrieving an assembly having a whipstock coupled to an anchor from a wellbore may comprise the steps of releasing the whipstock from the anchor in the wellbore, re-engaging the whipstock to the anchor, and retrieving the whipstock with the anchor from the wellbore. An apparatus for use in a wellbore may comprise a whipstock, a latch coupled to the whipstock, and an anchor operable to be selectively retrieved from the wellbore using the latch.
