Brittleness Evaluation in Shale Gas Reservoirs and Its Influence on Fracability
Energies, 2020 The brittleness index (BI) is a key parameter used to identify the desirable fracturing intervals of shale gas reservoirs. Its correlation with fracability is still controversial. There have been a variety of methods proposed that can estimate BI.

Mechanical mechanism of in situ stress ratio limit and its evolution simulation
Frontiers in Earth Science, 2022 In situ stress is a natural phenomenon. According to the Mohr–Coulomb criterion, it is found that when the ratio of principal stress (the ratio of maximum principal stress to minimum principal stress) of crustal rock mass in a certain environment exceeds
