... plays a significant role in hydraulic fracture initiation and propagation and in the interaction between hydraulic fractures and natural fractures, especially in unconventional reservoirs. This paper provides a detailed description of a geomechanical characterization and modeling study for evaluating...

Two scenarios are presented to explain the overall falloff behavior; moving-hinge closure with tip extension, and activation of secondary natural fractures. The validity of each scenario is examined using...

... gradients resulting from the pressure depletion due to a nearby producing well and the fluid leak-off due to opening of natural fractures are fine-tuned to account for asymmetry observed in the geomechanical modeling. The role of the natural fractures is emphasized and practical approaches to estimate...

... Abstract It is generally believed that creating a Stimulated Rock Volume (SRV) is a good thing. Completion engineers talk about creating complexity, geologists talk about stimulating a natural fracture network, geomechanicists highlight the importance of low stress anisotropy. But how much do...
