An analytical solution and numerical modeling study of gas hydrate saturation effects on porosity and permeability of porous media
MetadataShow full item record
A gas hydrate is a type of crystallized compound formed by small gas molecules and water under high pressure and low temperature. Natural gas hydrate reservoirs exist mostly in offshore areas of outer continental margins, and some also occur in permafrost areas. Worldwide methane content in gas hydrate accumulations has an estimated volume ranging from 500 Tcf to 1.2 million Tcf. Economic values of these gas hydrate reservoirs are tremendous. A better understanding of the properties of gas hydrate-bearing reservoirs could lead to the development of novel safe and economic production methods. ...
