... parity of relative mobility of injected fluids was observed with respect to relative mobility of displaced water at true residual oil saturation and interpreted relative mobility of a formed oil bank. These results indicate that in-situ foam propagation was present which enabled mobility control...

Therefore identifying the wettability of the reservoir will lead to appropriate implementation of improved/enhanced oil recovery practices in order to improve the economy of the project. The initial wettability state of the reservoir rock has...

..., interfacial tension (IFT) and residual oil saturation reduction by chemical. Proper coreflood experiments are critical to reduce these uncertainties. Careful matching of coreflood experiments in numerical simulations is also important which provides key inputs for full field forecast. Another important...

... under reservoir conditions, a single-well, multi-zone injection test using Log-Inject-Log (LIL) techniques was executed. The objectives of this test were to determine injectivity of ASP fluids and to estimate changes in residual oil saturation (S or ) in the near-wellbore region. This paper discusses...
