Abstract: A one trip interventionless method for fracking multiple intervals incorporates a remotely operated passage isolation valve for each interval. A screen backed by a base pipe is provided to route screened production through a shutoff valve before the production reaches the passage in the completion assembly. The shutoff valve is remotely operated as well. The fracking port is associated with a pressure responsive operator such as a j-slot mechanism with a spring return. The j-slot mechanism is behind a rupture disc so that it remains unaffected while other operations are going on in the wellbore. The rupture discs are set at different pressures for the intervals involved. Sequentially, each fracked zone is isolated and the zone above is opened with breaking the rupture disc and applying predetermined number of pressure cycles. The screen valves are remotely operated as needed after the fracking to initiate production from one or more intervals.

Abstract: A production string for use in a wellbore is disclosed that in a non-limiting embodiment includes a lower section that includes a first tubular having a first connection device at a top end thereof, and an upper section that includes a second tubular that sealingly slides against the first tubular, a second connection device associated with the second tubular configured to engage with the first connection device, and an expansion joint above the second tubular.

Abstract: A completion tool for gravel packing screens incorporates an added position to allow redirection of flow to a signal transmission tool at the needed flow rates to optimize signal to noise ratios by creation of a discrete flow path that channels the desired flow directly to the device and using the production tubing and upper annulus as the balance of the flow circuit. The Smart Collet® has a landing location for this position which is preferably between the circulation and reverse positions of the crossover tool. The wash pipe assembly can have a shifting tool that closes the sleeve over the gravel exit ports for the information transmittal such ports can thereafter remain closed because the gravel packing is complete but for the reversing out of excess gravel which happens above the gravel exit ports.

Abstract: A wet connection system including a first connector configured to connect to a first control line. The first connector including at least one first pathway arranged to fluidly communicate with the first control line, and a biased movable plug movable within the first connector; and, a second connector configured to connect to a second control line. The second connector including a second pathway in fluid communication with the second control line and a biased sleeve movable within the second connector; wherein the first and second connectors are each pressure balanced to prevent internal control line pressure. External borehole pressures from moving the plug and sleeve from their biased positions blocking the respective first and second pathways in the disconnected condition of the wet connection system.

Abstract: Devices and methods for mounting and/or isolating members within housings. In described embodiments, a compressible shape memory polymer is used to provide this isolation. Particular embodiments are described wherein exemplary electronic circuit boards are disposed within carrier housings along with one or more protective spacers formed of shape memory polymer.

Abstract: A splice carrier has a first end and a second end and a sleeve portion located at the first end. The splice carrier also includes a body portion extending between the first end and the second end and including one or more grooves disposed therein. The one of the grooves includes a receiving area configured to receive a mechanical splice.

Abstract: A helical backup element includes a tubular body of material and a helical opening in the tubular body.

Abstract: A downhole backup system includes, a tubular positionable within a downhole structure such that an annular space exists between the tubular and the downhole structure. The downhole backup system also includes, a plurality of wedges that are radially movably positioned within the annular space, and each of two opposing ends of the plurality of wedges are configured to completely cover the annular space at all possible radial positions of the plurality of wedges.
