.... The effect of heterogeneity on Enhanced Gas Recovery (EGR) in a system containing two non-communicating intervals was investigated with two parallel 2 m sand-packs of 5.4 and 2 Darcies (D). Methane was recovered by injection of either CO2, or flue gas from this heterogeneous system. The effect of gravity...

This paper shows that gravity drainage processes that inject blended fluids such as propane-methane or a steam-solvent tend to have an inherently unstable material balance due to the difference between dew point and bubble point...

In order to expedite this return, methane was injected as the chase gas in many of the earlier HCMF, but not any more due to the increased cost of methane. For a given gas...

The laboratory results showed that, during low velocity displacement of methane by flue gas in a homogeneous linear sand- pack, molecular diffusion has a dominating effect on the recovery of marketable methane. Reasonable values of molecular diffusion coefficient for different gas/gas...

... is assumed to be laterally infinite. This theory, referred to by Butler as LinDrain Theory in his writings, is generalized here to the case when dissolved gas is present. The dissolved gas is taken to be methane and it is assumed that methane is soluble in the oil phase but not in the water phase. Dead...

Incineration is a proven method to reduce greenhouse gas emissions because the global warming potential (GWP) of methane is 21 times greater than the GWP of CO 2 . Hence, the complete combustion process that incineration offers reduces the global...

... of LNG include a study to determine the effect of its chemical composition on the vapourization rate (1) . The results of this study indicated that the vapourization rate of LNG differs from that of pure methane, especially in the late stages of a spill. The differences were attributed to the ethane...
