Auxiliary conduits that run through a packer body or seal are equipped with thermally responsive valve members that with a time exposure close off the conduits to create zonal isolation across one or more packers after a gravel pack. The heat source can also be added to the well fluids to control the speed of the process either in the form of heaters or reactive chemicals that create an exothermic reaction. The valve material can be shape memory polymer.

Isolation packer with automatically closing alternate path passages

An isolation method is described for gravel packed zones separated by at least one packer and having an auxiliary conduit passing through the packer into adjacent zones. The conduit includes at least one each of a shunt tube, flow housing, annular space, and isolation valve housing. The flow housing, the annular space, and the isolation valve housing are all annular and formed between two concentric pipes. The method includes running in an assembly of screens isolated by at least one packer with at least one auxiliary conduit extending into adjacent zones defined by the packer when the packer is subsequently set. The method also includes closing flow in said conduit to prevent flow into shunt tubes during production based on creating a flow barrier in the annular space, the flow housing, or the isolation valve housing, the shunt tubes supplying slurry through the auxiliary conduit prior to the production.

A method of completing a subsea borehole including connecting a first vessel to a subsea wellhead assembly via a riser. A borehole is drilled with a drill string communicated to the subsea wellhead assembly through the riser. A lower completion assembly is run on a service string into the borehole through the riser. At least two barrier valves of the lower completion assembly are set with the service string in order to form a mechanical barrier to fluid flow with each of the at least two barrier valves. The riser is disconnected from the subsea wellhead assembly. An upper completion string is run through open water to the borehole and connected to the lower completion assembly. An lower completion assembly for a subsea borehole is also included.
