摘要： An interventionless downhole screen that is resistant to plugging during run-in-hole operations and a method for remotely actuating the screen. The screen includes a perforated sleeve that is slideably disposed coaxially with a perforated tubular member. When running, the sleeve is in a closed positioned with its openings offset from the apertures in the tubular member, thereby blocking flow through the screened openings, while a check valve through the tubular member allows fluid ingress. To actuate for production, the tubular member is pressurized, which moves a piston into ratcheting engagement with the sleeve. A subsequent depressurization allows the piston to return to its original position, carrying with it the sleeve to an open position where the sleeve and tubing perforations are aligned for allowing fluid flow into the tubular member.

摘要： A jumper tube is connected to a shunt tube of a well screen assembly by positioning the jumper tube end to end, adjacent with the shunt tube. A spring clip is then flexed over a profile of a coupling and allowed to snap into gripping engagement of the coupling, thereby retaining the jumper tube relative to the first screen assembly.

摘要： An example tubing string may at least partially define an internal bore. The tubing string may include an expandable packer and a permeable barrier. The tubing string may further include a remotely-controllable valve responsive to at least one downhole trigger condition, such as a downhole pressure or temperature condition. The remotely-controllable valve may provide selective fluid communication through the permeable barrier between the internal bore and an annulus outside of the permeable barrier. The remotely-controllable valve may function as at least one of a fluid-loss control valve in a completion string assembly or a circulation valve about a completion string assembly.

摘要： A completion joint 100 has two sand control jackets 120A-B connected on each end of an intermediately-mounted inflow control device 130. Both jackets 120A-B communicate with a housing chamber 155 through dedicated open end-rings 140A-B. The basepipe's flow openings 118 are isolated from this housing chamber 155 by a sleeve 160 fitted with flow ports 170. The housing 150 is removable to allow access to the flow ports 170 for pinning to configure the ports 170 open or closed for a given implementation.

摘要： A flow control assembly for regulating fluid flow in a wellbore is disclosed. A remote-open ICD is opened in response to swelling of a swellable actuator. The swellable actuator can move a flow regulator radially, circumferentially, etc., such that flow is allowed through the regulator. Alternately, the swellable actuator can move one or more valve members to an open position thereby allowing fluid to flow across the valve and to the flow regulator. The swellable actuator can be swelled in response to introduction of chemicals or heat. A guide mechanism can be used to control swelling of the actuator or movement of the regulator device or valve member.
