Abstract: In a completion for producing methane the bottom hole assembly has a base pipe with porous media surrounding it for equalizing flow along the base pipe. A shape memory polymer foam surrounds the porous media. The borehole can be reamed to reduce produced methane velocities. Surrounding the shape memory polymer is an exterior layer of consolidated proppant or sand that can self-adhere and/or stick to the polymer foam. The proppant or sand can be circulated or squeezed into position although, circulation is preferred. The borehole may enlarge due to shifting sands in an unconsolidated formation as the methane is produced. The bottom hole assembly helps in fluid flow equalization and protects the foam and layers below from high fluid velocities during production.

Abstract: Wall openings in a mandrel of a liner hanger/packer are eliminated and setting is accomplished with pressure against a landed object in a running tool. The wall of the running tool leads to a sealed annular space with a movable seal attached to a setting sleeve and the other end is a packer cup supported by the running tool. The setting sleeve sequentially sets the slips and releases the running tool followed by setting the packer seal. Optionally a dog sub can be used to set with set down weight on the setting sleeve. The set positions are locked in. The slips can be alternatively set with release of a contained spring force. The setting sleeve seal can be sheared out to allow removal of the running tool.
