Firstly, rock permeability and porosity are tested during multi-cycle injection and production to quantitatively analyze the impact of salt precipitation and formation water evaporation...

... analysis procedure in numerous unconventional reservoirs. We measured the permeability of the matrix rock and the permeability of an embedded fracture, as well as the porosity for several 1-1/2-inch by 2-inch cores. Then, we used the measured permeabilities and porosities in the analysis of multi-rate...
