... accompanying hydraulic stimulation, and survey design. In the upper diagonal half of the time shifts map, the size of the 4D anomaly band merely depends on the fracture aspect ratio and the induced confining horizontal stress. However, the stretch of the 4D fracture shadowing seen in the lower diagonal half...

... the vertical and horizontal Young s moduli and Poisson s ratios, as well as the minimum horizontal stress. The coefficient of determination (R2) and normalized root mean square error (RMSE) are used to assess the performance of the model on the test dataset. Best R2 (0.99) and normalized RMSE (0.015...

... in-situ stress is significantly larger than the horizontal stresses. This stress regime increases the chances of axial fracture initiation and high near-wellbore fracture tortuosity. Optimizing these perforating variables can result in lower breakdown and treatment pressures, a reduction of near-wellbore...

Minifrac test data were analyzed to determine the minimum horizontal stress. The FMI logging and stress polygon method were...

... stress ( h) and maximum horizontal stress ( H) need to be determined (Peng and Zhang, 2007). The vertical (or overburden) stress at a depth is considered as the weight imposed by the overlying formations. This is calculated through integration of the bulk density log and gravitational constant from...
