“…In contrast, undrained responses are frequently observed in field measurements, especially in oil and gas applications. A number of papers, such as those by Cheng et al (1993Cheng et al ( , 2008, Ghabezloo et al (2008), Chen et al (2009), Belmokhtar et al (2017), and Wong (2017) [15][16][17][18][19][20][21], have studied the isotropic poroelastic behavior of different porous media materials (such as concrete, granite, and sandstone) under undrained conditions through numerical simulations, predicting various parameters, such as the drained modulus, storage modulus, and effective stress coefficients.…”

The exploration of fractured-vuggy carbonate reservoirs usually involves hydraulic fracturing to maximize recovery. At present, effectively communicating natural discontinuities is a technical challenge. In this article, we investigated the origin and propagation of cracks in fractured-vuggy reservoirs using discrete element hydraulic fracturing simulations that included poromechanical effects. A particular focus on the microscopic force-displacement symmetry of adjacent pore pressures is introduced. Our results demonstrate that the poromechanical effect significantly increases the strength of overpressurized reservoir formations. Moreover, the effect of injected fluid viscosity on the hydraulic fracturing effectiveness was studied through two simulation tests. The outcomes highlight the critical influence of fluid viscosity on the propagation of micro-cracks in overpressure fractured-vuggy reservoirs.
