Abstract: A completion assembly defines a throughbore and comprises an isolation valve configurable between an open state (permitting fluid to flow through the throughbore) and a closed state (preventing fluid from flowing through the throughbore). A method for use in installing the assembly into a wellbore in a single trip comprises running the assembly into the wellbore with the valve in the open state until a downhole end of the assembly reaches a target position; injecting a fluid through the throughbore and the valve when the valve is in the open state; configuring the valve into the closed state; and performing a pressure integrity test of the throughbore above the valve. The valve is configurable between the open and closed states without any requirement for the valve to be mechanically engaged by an activation member or a tool whilst the valve receives power from a power source.

Abstract: A technique facilitates rapid transitioning of a valve, e.g. a gate valve. According to an embodiment, a system comprises a valve actuator constructed for coupling with a valve to actuate the valve between closed and open positions. Hydraulic actuation fluid may be supplied to the valve actuator under pressure via a hydraulic supply system to enable selective shifting of the valve actuator, and thus the valve, from a closed position to an open position. The system also comprises a dump tank coupled to the valve actuator in a manner to receive hydraulic fluid. In a rapid valve actuation operation, e.g. closing operation, the dump tank receives hydraulic fluid from the valve actuator rather than returning the hydraulic fluid to the hydraulic supply system. This, in turn, enables rapid shifting of the valve actuator and thus rapid shifting of the valve.

An opening device is operable to move the one way valve member to a valve open position upon receipt of an engagement signal from the command center. The opening device is inoperable after the predetermined time. The one way valve member is operable to function as a one way valve after the predetermined time.

Abstract: A flow control mechanism includes a housing defining a through bore and a cavity contiguous with the through bore, and a barrier received within the cavity of the housing. The barrier is moveable between a sealing position in which fluid flow through the housing is permitted in one direction through the housing and blocked in an opposite direction, and a non-sealing position in which the flow control mechanism is configured to receive an attachment member. An actuating mechanism returns the barrier to the sealing position when the attachment member separates. The actuating mechanism may be an elastomeric band that is in a non-stretched state when the barrier is in the sealing position and in a stretched state when the barrier is in the non-sealing position. The barrier returns from the non-sealing position to the sealing position by action of torque of the stretched flexible member as the flexible member returns to the non-stretched state.

Abstract: Apparatus, systems, and methods for reverse circulation cementing a tubular string in a wellbore. One such method includes reverse circulating cement slurry down an annulus defined between the tubular string and the wellbore. During the reverse circulation, a flow control device located in the tubular string is closed to prevent, or at least reduce, flow of the cement slurry from the annulus into the tubular string. The closure of the flow control device causes a pressure pulse in the wellbore. After the flow control device is closed, the reverse circulation is stopped. During a time interval between the closure of the flow control device and the stoppage of the reverse circulation, a shock absorber associated with the flow control device absorbs the pressure pulse in the wellbore so that a pressure in the wellbore is maintained within an acceptable range.
