Consolidation and Permeability of the B1 and D1 Gas Hydrate Bearing Sands and Associated Seal Sediments of the Extended-Duration Gas Production Test Site on the Alaska North Slope.

overall increase in the horizontal permeability in the reservoir at the end of the depressurization (i.e., postgas production) compared to that before the gas production. This is because the reservoir sediments at this site are less compressible, so the permeability reduction by stress increase is not as significant as the hydrate-loss-induced permeability increase.
