Claim:
1. A method of creating an artificial reservoir to allow for production of methane from an unconsolidated wellbore formation surrounding an open hole borehole comprising methane hydrate, sand or other sediments, said method comprising: delivering a consolidated artificial barrier to the open hole borehole near the unconsolidated wellbore formation using a bottom hole assembly; wherein the artificial barrier is adapted to reduce erosion of the surrounding formation by equalizing through the use of depressurization devices the disassociation of methane hydrate across an interval of the bottom hole assembly while not stressing the surrounding formation; using a shape memory porous member whose dimension increases radially in the open hole borehole and at least one of a porous media and consolidated proppant in said artificial barrier; and enlarging the artificial barrier to leave an annular gap to the open hole that remains during subsequent methane production; producing methane.
