Fracturing criterion of rock hydrofracturing considering pore pressure effect

open access: yesFrontiers in Earth Science, 2023
Traditional hydraulic fracturing theory believes that as the initial pore pressure increases, the breakdown pressure of the rock will decrease. Previous experimental studies have shown that the breakdown pressure of rock hydraulic fracturing may increase
