Jang, J., Waite, W.F., Stern, L.A., Collett T.S., and Kumar, P., 2018, Dependence of sedimentation behavior on pore-fluid chemistry for sediment collected from Area B, Krishna-Godavari Basin, during India's National Gas Hydrate Program, NGHP-02: U.S. Geological Survey data release,


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 (fines) to the change [...]

“Sedimentation test definitions of the accumulation and depositional interfaces.”

The data in this data release show how pore-fluid chemistry changes alter the interactions between fine-grained particles. The sediment for this study comes from above, below and within a gas hydrate-bearing reservoir in the Krishna-Godavari Basin, offshore eastern India. Of particular interest is how the fine-grained behavior changes as the pore water becomes more fresh, because pore-water freshening will occur as methane is extracted from the gas hydrate as an energy resource.
