Introduction,permeable aquifers and reservoirs. On the one hand, oil has a specific gravity of around 0.8–0.9 g/cm., while subsurface waters range in specific gravity from around 1 g/cm. to about 1.3 g/cm. for hypersaline saturation conditions. Thus, there is a vertical buoyancy drive on oil of around 0.1 to 0.5胰脏 发表于 2025-3-26 02:57:39

Steady-State Oil Stringers in Capped Aquifers,sand box with a Plexiglas front had a rubber stratum embedded in the sand to simulate an impermeable upper boundary to a reservoir sand. The box was filled with water under pressure, and then colored alcohol was added. After settling to equilibrium, the alcohol was found to be at the structural highVEST 发表于 2025-3-26 16:31:16
