Experimental Investigation on Pore-Permeability Evolution of Tight Carbonate Rocks in SC-CO2 Acidizing
The Lower Paleozoic carbonate reservoirs in the Yan’an Gas Field are characterized by low porosity, low permeability, and strong heterogeneity, which make effective stimulation difficult. Although supercritical CO2 (SC-CO2) acidizing has shown promising results in field applications, the effects of SC-CO2 concentration...
