Porosity factor of gas saturated reservoirs of I zone is in average 0.24; permeability is 0.632 μm 2 , factor of residual water saturation is 0.24. II zone is presented...

... adjacent to each other in the same layer parallel to the bedding in order to ensure maximum similarity. Residual water saturation was simulated in the samples and then they were saturated with kerosene. Then permeability test was carried out with simulation of formation acidizing. Two stages...
