Injecting CO2 into a reservoir disturbs the geostress field. which leads to variations in the permeability of caprock and affects its sealing performance. In this paper. the evolution characteristics of the permeability of Yingcheng mudstone were experimentally studied during deviatoric compression under different confining pressures. https://poolsproductscanadas.shop/product-category/jandy-trufit-bubbler-parts/
