... was injected into the core. The formation brine was injected at three different rates and a stabilized pressure drop across the core was measured for the individual injection rate. After injecting the several pore volumes of formation brine the stabilized pressure drop was recorded for the corresponding...

... production process for any given pressure drop. (3) The gas adsorption/desorption isotherm is described by a Langmuir equation. Thus, the desorption coefficient can be written as: (1) k a d s = ρ s V s t d ⋅ ∂ ( V L P P L + P ) ∂ t...

... to study the effect of injected brine salinity. The interfacial tension values were measured for the different brines and heavy crude oil systems. The corefloods were interpreted using reservoir simulation, by history matching the experimental oil RF and the pressure drop across the core. A detailed focus...
