Numerous simulation runs were conducted to investigate the detailed influence of fluid flow direction, capillary pressure, reservoir pressure, temperature, production rate, and injection timing. Simulation results indicate...

The site activation depends on the thermodynamical equilibrium assumed by Henry s or k-values laws but also on the mechanical equilibrium described by the Laplace s law. These two equilibriums depict the two sides of the gas liquid interface combining...

To do so at the boundary is erroneous. This error can be avoided by choosing boundary conditions that curtail flow through the boundaries...
