摘要:
A system that is usable with a wellbore includes a deployment tool that is attached to a conveyance device and has an unexpanded state and an expanded state. The system also includes a scrolled tubular, such as a sand screen, which is attached to the deployment tool. The tubular is scrolled around the deployment tool in the unexpanded state with the scrolled tubular having an outer diameter that is less than an inner diameter of a tubing that is located in the wellbore. The tubular is then unscrolled to expand against a surface in an expanded state of the tubular.

A technique is provided to facilitate pumping of fluids in a well environment. A submersible pumping system having a submersible pump incorporates features that manage thrust loads resulting from rotating impellers. The thrust reducing features cooperate with the action of the impellers in one or more pump stages to reduce forces otherwise acting on certain pump related components.

To perform a cleanout operation in a wellbore, a cleaning tool having a coiled tubing and an electrical pump assembly is run into the wellbore. The electrical pump assembly that is located in the wellbore is activated. In response to fluid flow generated by the electrical pump assembly, removal of debris from the wellbore is caused by directing fluid containing the debris into the coiled tubing for delivery to an earth surface.

A system and method for completing a well with multiple zones of production is provided, including a casing having a plurality of valves integrated therein for isolating each well zone, establishing communication between each underlying formation and the interior of the casing, delivering a treatment fluid to each of the multiple well zones, and filtering produced fluids from each underlying formation.
摘要:
A control line can be positioned in a downhole completion. For example, the control line can be deployed in a protected position along a stinger to reduce the potential for damaging the control line during installation, removal or operation.
摘要:
An apparatus and method for measuring the puncture resistance of an aluminum can that has improved repeatability and more accurately simulates end-use punctures. A penetrator that moves in a horizontal direction and is driven by a falling weight impacts a pressurized aluminum can containing liquid. The aluminum can is impacted by a penetrator of the puncture gauge in an area below the liquid level. Various sensors, such as a load cell and a displacement transducer, measure data from the impact and the data is compiled and analyzed by a data acquisition system.
