An apparatus that is usable with a well includes a tubular assembly and an expansion tool. The tubular assembly has a radially contracted state and includes a restriction. The restriction is adapted to catch an object that is deployed into the well to form a fluid barrier when caught by the restriction. The expansion tool is deployed downhole with the tubular assembly inside a tubing string. The expansion tool is adapted to deform the tubular assembly to anchor the tubular assembly to the tubing string.

Isolation assembly

A technique facilitates coupling of sections of tubing, e.g. a casing and a liner. A first tubing is positioned at a desired location, and then a second tubing is deployed through an interior of the first tubing until predetermined regions of the first tubing and the second tubing are in proximity to one another. A molten metal material is located between the first tubing and the second tubing at the predetermined regions. The molten metal material is then solidified to secure the second tubing to the first tubing.

System and methodology for coupling tubing

A tool for deploying a wellbore plug in a well using flowable eutectic material is disclosed. A tool having a mandrel, an obstruction, and a flowable quantity of eutectic material in a solid state is positioned in the wellbore. The obstruction is actuated and the flowable material is heated to melt. The obstruction supports the flowed material as it cools to form a plug in the wellbore.

Methods of deployment for eutectic isolation tools to ensure wellbore plugs

A rigless sand-control tool string is for use in a wellbore having plural zones. The tool string includes plural flow port assemblies, and plural screen assemblies connected to corresponding circulation port assemblies. Each set of one of the flow port assemblies and one of the screen assemblies is configured to perform sand control with respect to a corresponding zone of the wellbore. The flow port assemblies are selectively activatable to allow selective performance of sand control with respect to the corresponding zones.
