摘要： A completion system that is usable with a well may include a packer, a screen, an isolation valve and an annulus communication valve. The screen communicates well fluid between an annulus of the well and an interior passageway of the completion system. The isolation valve is radially disposed inside the screen to control communication through the screen between the annulus and the interior passageway. The annulus communication valve is located downhole of the packer and uphole of the screen to control communication with the annulus of the well. The packer, screen, isolation valve and the annulus communication valve are adapted to be run downhole as a unit into the well as a single trip completion.

摘要： The invention is a system and method used to seal between an open wellbore and a tubing by bringing the wellbore wall inwardly so as to enable sections of earth from the wellbore wall to create the required seal against the tubing. The earth sections that make up the seal can be created by collapsing the relevant parts of the wellbore wall inwardly or by causing the relevant parts of the wellbore wall to swell inwardly.

摘要： A system and method is provided for pressure testing a tubing string. A valve is utilized within the tubing string to enable selective application of pressure in the tubing above the valve. However, between pressure tests, the valve may be opened to allow fluid flow into the tubing. Thus, the tubing string may readily be moved, for example, downhole into a wellbore with periodic application of pressure to test the tubing.

摘要： An apparatus usable in a subterranean well includes a valve, a first mechanism, a second mechanism, and a lock. The valve controls communication between an exterior region that surrounds the valve and an inner passageway of the valve. The first mechanism causes the valve to transition from a first state to a second state in response to pressure in the exterior region. The second mechanism causes the valve to transition between the first state and the second state in response to a pressure differential between the exterior region and the inner passageway. The lock fixes the valve in one of the states.
