.... The methodology includes data integration, discrete fracture network modeling, rock mass property characterization, and numerical 3D stress modeling. Results indicate that wellbore stability is influenced by horizontal stress variability and low-strength reservoir rock due to high porosity or natural fractures...

.... The sensitivity analysis was carried out, including brittleness, natural fractures and in-situ stress condition. The results show that under the same stress condition, the brittle sample behaves a lower breakdown pressure and a faster propagation rate, while plastic sample generates an appear asymmetric fracture...

... points. Using geomechanical models, well logging data, and core analysis, the study examines the key mechanisms of deformation, including large dogleg severity, high incidence angles, and natural fractures. Three primary deformation types were identified: Type I due to large dogleg severity, Type II from...

... was employed to simulate fracture propagation, incorporating key reservoir properties such as in-situ stress variations, natural fracture networks, and rock brittleness. The model's accuracy was validated by comparing the simulated hydraulic fracture geometry with microseismic data and pumping pressure curves...

... shale gas pad consisting of four horizontal wells. A detailed geomechanical analysis was conducted, examining stress distribution and rock brittleness. A natural fracture model was developed, identifying four groups of fractures with lateral scales ranging from tens of meters to kilometers. A total...

... ABSTRACT: To mitigate drilling risks and optimize the economic and efficient utilization of carbonate resources, precise reservoir characterization is essential. However, predicting the distribution of natural fractures and vugs in carbonate reservoirs using seismic and well data is fraught...

... ABSTRACT: Negative pore pressure induced during unconventional energy production may provide new insights into assessing and mitigating injection-induced post-slip of rock fractures. Using triaxial experimental setup in the laboratory, we sheared sawcut, filled, and natural fractures...
