Abstract: A pressure control system includes a housing having a bore and a first pair of opposed rams positioned within the housing. The first pair of opposed rams is configured to move between a retracted position and an extended position relative to the bore. The pressure control system further includes a rotating control device (RCD) seal assembly, which includes a frame that is configured to couple to the first pair of opposed rams while the first pair of opposed rams are in the extended position relative to the bore, an annular seal element coupled to the frame, and a bearing assembly positioned between the annular seal element and the frame. The annular seal element is configured to seal about a tubular within the bore, and the bearing assembly is configured to enable the annular seal element to rotate relative to the frame and the first pair of opposed rams.

Abstract: A downhole wellbore treatment system for and a method of treating an inner surface (FT) of a wellbore (W) is provided. The system comprises an elongate conduit (50) such as a flexible hose (50) for conveying treatment fluid from the surface (P; C) to a treatment head (80) adapted to be inserted into the wellbore (W). The treatment head (80) has a nozzle (83) providing an outlet from the conduit (50) for creating a jet of treatment fluid directed at the inner surface (FT) of the wellbore (W). The treatment head (50) is rotationally disconnected from the conduit (50) by a swivel device (70), allowing rotation of the head (50) relative to the conduit (50) during jetting of the treatment fluid. The elongate conduit (50) is reelable (10) and is inserted into the downhole wellbore (W) from a reel (10) at the surface, through a pressure control device (40) containing wellbore pressure within the downhole wellbore (W) during insertion of the elongate conduit (50) from the reel (10).

Abstract: A rotating flow head (RFH) has a housing having an internal bore with diameter substantially equal to that of a riser and at least one flow port proximate one longitudinal end thereof. First and second arrays of radially extensible and retractable locking elements are disposed circumferentially around the RFH housing. The RFH has a bearing assembly (BA) housing having an exterior diameter selected to fit within the internal bore of the RFH housing so as to provide an annular space therein. The BA housing has profiles for engaging one of the arrays of locking elements when extended. A mandrel is rotatably, sealingly supported within the BA housing. Another end of the BA housing and the other array of locking elements have features cooperative to provide longitudinal force on the BA housing to energize a seal element disposed in the annular space when the other array is extended.

Abstract: The disclosure provides a subsea overload release system and method. The disclosure provides a releasable connection system that can be overridden during an overload condition, and is resettable in a subsea location in situ. During normal operation, a collet sleeve is slidably engageable with a collet having one or more fingers that can releasably couple a first member with a second member. During an overload condition, an overload piston acting on fluid in an overload reservoir causes an overload pressure and a rupture or other release of fluid through an overload pressure member, causing the overload reservoir to at least partially collapse. The collapse allows the system to extend and force open the fingers to disengage the second member from the first member. When the overload symptom is rectified, the overload reservoir can be reset and the overload pressure member reset or replaced without requiring repairs above sea surface.
