Fine-grained sediments, or “fines,” are nearly ubiquitous in natural sediments, even in the predominantly coarse-grained sediments that host gas hydrates. Fines within these sandy sediments can be mobilized and subsequently clog flow pathways while methane is being extracted from gas hydrate as an energy resource. Using two-dimensional (2D) micromodels to test the conditions in which clogging occurs provides insights for choosing production operation parameters that optimize methane recovery in the field. During methane extraction, several processes can alter the mobility and clogging potential of fines: (1) fluid flow as the formation is depressurized to release methane from gas hydrate, (2) shifting pore-fluid...

Understanding how effectively methane can be extracted from a gas hydrate reservoir requires knowing how compressible, permeable, and strong the overlying seal sediment is. This data release provides results for flow-through permeability, consolidation, and direct shear measurements made on fine-grained seal sediment from Site NGHP-02-08 offshore eastern India. The sediment was collected in a pressure core from the Krishna-Godavari Basin during the 2015 Indian National Gas Hydrate Program Expedition 2 (NGHP-02). Gas hydrate is a crystalline solid that forms naturally in the sediment of certain marine and permafrost environments where pressure is relatively high (equivalent to the pressure measured ~300 meters water...

One goal of the Indian National Gas Hydrate Program's NGHP-02 expedition was to examine the geomechanical response of marine sediment to the extraction of methane from gas hydrate found offshore eastern India in the Bay of Bengal. Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular cages in a lattice of water molecules. Methane gas hydrate is a potential energy resource, but whether extracting methane from gas hydrate in the marine subsurface is technically and economically viable remains an open research topic as of 2018. This data release provides insight about a poorly quantified aspect of this process: the reaction of fine-grained sediment particles...

During the spring and summer of 2015, the U.S. Geological Survey participated in India’s National Gas Hydrate Program NGHP-02 expedition in the Krishna-Godavari Basin offshore eastern India. The expedition included conventional and pressure coring of sediment, samples of which were transferred to the U.S. Geological Survey in Woods Hole, MA for post-cruise testing. This data release contains measurement results for physical properties measured on recovered core material, including measurements on gas-hydrate-bearing sediment preserved in pressure cores, and physical properties of gas hydrate-free sediment recovered from conventional cores. This work is part of an international NGHP-02 collaboration culminating in...
