摘要： An acoustic control system wirelessly operates a subsea latching assembly or other subsea device, such as an active seal. The acoustic control system may control a subsea first accumulator to release its stored hydraulic fluid to operate the latch assembly or other subsea device, such as an active seal. An RCD or other oilfield device may be unlatched or latched with the latching assembly. The acoustic control system may have a surface control unit, a subsea control unit, and two or more acoustic signal devices. A valve may allow switching from an umbilical line system to the acoustic control system accumulator.

摘要： A method of operating an isolation valve in a wellbore includes: deploying a work string into the wellbore through a tubular string disposed in the wellbore. The work string comprises a deployment string, a shifting tool, and a bottomhole assembly (BHA). The tubular string comprises the isolation valve and an actuator. The method further includes rotating the actuator using the shifting tool, thereby opening or closing the isolation valve. The isolation valve isolates a formation from an upper portion of the wellbore in the closed position.

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 method of drilling a wellbore includes drilling the wellbore through a formation by injecting drilling fluid through a drill string and rotating a drill bit. The drill string includes a shifting tool, a receiver in communication with the shifting tool, and the drill bit. The method further includes retrieving the drill string from the wellbore through a casing string until the shifting tool reaches an actuator. The casing string includes an isolation valve in an open position and the actuator. The method further includes sending a wireless instruction signal to the receiver. The shifting tool engages the actuator in response to the receiver receiving the instruction signal. The method further includes operating the actuator using the engaged shifting tool, thereby closing the isolation valve and isolating the formation from an upper portion of the wellbore.

摘要： In one embodiment, a method for drilling a wellbore includes injecting drilling fluid into a top of a tubular string disposed in the wellbore at a first flow rate. The tubular string includes: a drill bit tubular joints connected together, a longitudinal bore therethrough, and a port through a wall thereof. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The cuttings and drilling fluid (returns) flow to the surface via an annulus defined between the tubular string and the wellbore. The method further includes rotating the drill bit while injecting the drilling fluid; remotely removing a plug from the port, thereby opening the port; and injecting drilling fluid into the port at a second flow rate while adding a tubular joint or stand of joints to the tubular string. The injection of drilling fluid is continuously maintained between drilling and adding the joint or stand to the drill string. The method further includes remotely installing a plug into the port. A clamp specially adapted to carry out this method is also disclosed.

摘要： Sealing elements have lubricating seal profiles for communicating fluid between the sealing elements and the sealed drill string tubular or other oilfield component while the sealed drill string tubular or other oilfield component rotates or moves vertically relative to the seal elements. The same fluid used for drilling may also be used for seal lubrication, such as water, drilling fluid or mud, well bore fluid or other liquid or gas. The sealing elements may be disposed with a seal housing, which may be positioned with a marine riser, or subsea without a marine riser. The seal housing may prevent rotation of the seal elements with the sealed drill string tubular or other oilfield component. Alternatively, the seal housing may be an RCD that allows the sealing elements to rotate. The lubricating seal profiles include a wave pattern, a saw-tooth high film pattern, a downwardly inclined passageway pattern, an upwardly inclined passageway pattern, and a combined upwardly and downwardly inclined passageway pattern. In one embodiment, a stripper rubber seal element may have a lubricating seal profile on the inwardly facing bore surfaces of both its nose and throat sections for sealing with drill string tubulars and other oilfield components having different diameters. Dual seals with two annular spaced apart sealing surfaces, with or without lubricating seal profiles, may seal with a drill string tubular or other oilfield component. In another embodiment, differential pressures across two seal elements may be managed by filling the cavity between the two sealing elements with cuttings-free drilling fluid, mud, water, coolant, lubricant or inert gas at desired amounts of pressure.
