... Abstract Geomechanics 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...

... fracture evolution. Moreover, microseismicity-derived deformation fields are integrated with volumetric estimates made by rate transient analysis to calibrate spatially-constrained SRV models. Through the case study, we give evidence of fracture containment, evaluate the role of natural fractures...

... Abstract Productivity of hydraulically stimulated unconventional wells depends greatly on the successful interconnection of the enhanced permeability and the natural fracture system. Such success is achived by proper understanding of the distribution of mechanical properties of the rock...

... Abstract Natural fractures, fissures, and microfractures are well-known contributors to production performance of shale reservoirs. Complex fracture geometries can be generated by either small-scale fracturing, DFIT, or large volume fracture stimulation, because the activation of pre-existing...

... the test. DFIT data in the Duvernay shale are analyzed using pressure transient analysis methods. 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...

... Abstract Unconventional reservoirs, including shale formations and many tight-gas sands, contain natural fractures, fissures, faults, and microfractures that contribute to the rock flow capacity. In most cases, core-measured permeability, and especially crushed-core permeability measurements...

... 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...

The UFM simulates interwell and interstage stress shadows and honors both sequential fracturing and zipper fracturing scenarios...

..., or heterogeneity, is more than just natural fractures. Stress and bedding plane character need to be incorporated to properly understand how SRV evolved during the stimulation process. SRV may be facilitated by natural fractures in association with a low horizontal stress anisotropy. Ideally natural fractures...
