A Gas-Solid Free Boundary Problem for a Compressible Viscous Gas

SIAM Journal on Mathematical Analysis, 2003
A one-dimensional free-boundary problem is formulated to describe a phase transition of solid into compressible viscous gas with a prescribed density jump at the phase transition line. Initial data are found to permit global existence of solutions which are close to a combination of traveling and rarefaction waves.

Theoretical model and numerical solution of gas desorption and flow mechanism in coal matrix based on free gas density gradient

, 2021
Understanding the gas migration mechanism is of vital significance to predict gas production from Coal-Bed Methane (CBM) wellbores. At present, the widely used Fick’s law of diffusion in coal matrix has been questioned by more and more researchers.

Distributions of gas hydrate and free gas accumulations associated with upward fluid flow in the Sanriku-Oki forearc basin, northeast Japan

Marine and Petroleum Geology, 2020
We applied automated velocity analysis to a 3D seismic data volume to obtain a high-resolution seismic velocity model that we used to investigate the influence of fluid behavior on the subsurface distribution of gas in the Sanriku-Oki forearc basin ...

Application of constrained AVO inversion: 2-D modelling of gas hydrates and free gas in Mahanadi basin, India

Journal of Natural Gas Science and Engineering, 2020
We present an application of Constrained Amplitude versus Offset (AVO) inversion for 2-D modelling of gas hydrates and free gas saturation in the Mahanadi offshore basin. In order to reliably model gas hydrate distribution, it is essential to derive both
