Modeling Hydrates and the Gas Hydrate Markup Language
Natural gas hydrates, as an important potential fuels, flow assurance hazards, and possible factors initiating the submarine geo-hazard and global climate change, have attracted the interest of scientists all over the world. After two centuries of hydrate research, a great amount of scientific data on gas hydrates has been accumulated. Therefore the means to manage, share, and exchange these da...
متن کاملApplication of the cell potential method to predict phase equilibria of multicomponent gas hydrate systems.
We present the application of a mathematical method reported earlier by which the van der Waals-Platteeuw statistical mechanical model with the Lennard-Jones and Devonshire approximation can be posed as an integral equation with the unknown function being the intermolecular potential between the guest molecules and the host molecules. This method allows us to solve for the potential directly fo...
متن کاملBattelle Pacific Northwest Division Gas Hydrates Assessment Assessment of Current Technologies for Producing Natural Accumulations of Gas Hydrate
Vast quantities of natural gas are held in hydrate form in geologic reservoirs in sub-oceanic sediments and arctic permafrost zones (KVENVOLDEN, 1988; SLOAN, 1998), where conditions of high pressure and low temperature are within the hydrate stability region. In 1995, the U.S. Geological Survey (USGS) conducted a study to assess the quantity of natural gas hydrate resources in the United States...
متن کاملI / I ratios and halogen concentrations in pore waters of the Hydrate Ridge : Relevance for the origin of gas hydrates in ODP Leg 204
We report iodine and bromine concentrations in a total of 256 samples of pore waters collected from all nine sites of ODP Leg 204, Hydrate Ridge. In a subset of these samples, we have also determined iodine ages in the fluids using the cosmogenic isotope I (T1/2 = 15.7 Ma). The presence of this cosmogenic isotope combined with the strong association of iodine with methane allows the identificat...
متن کاملOcean Drilling Program Leg 204 Scientific Prospectus Drilling Gas Hydrates on Hydrate Ridge, Cascadia
During Ocean Drilling Program (ODP) Leg 204, we will drill a transect of sites through the gas hydrate stability zone on the southern part of Hydrate Ridge on the Cascadia accretionary margin offshore Oregon. Massive hydrates are present at the seafloor there, and high-resolution threedimensional seismic data indicate a complicated subsurface plumbing system. The transect will cover two distinc...
