.../L NaCl. Also, as N 2 concentration increased in the injection gas, the permeability reduction and the sweep efficiency decreased. In the case of DI water and 50% N 2 , the permeability reduction was 12%, and the residual water saturation was 47%. Based on these observations, CO 2 sequestration...

... genetic unit (RGU). This case study has successfully developed and tested this new methodology to predict residual water saturation. Combinations of wireline logs and core data from a short 7m RGU interval in a North sea well were used to train the GFNN predictors. These were then applied to predict...

... for the high values of residual water saturation. Introduction Relative permeability is a primary parameter in determining the response of coal-seam reservoirs. Despite the importance of relative permeability, measurements are infrequent and very few recorded examples appear in the literature. The main...
