Simulating gas production from hydraulic fracture networks : a case study of the Barnett shale
… shown that the hydraulic fracturing of vertical wells produces an extremely complex network of fractures, and the work presented here focuses on modeling these fracture networks to gain a better understanding of how hydraulic fractures perform in the Barnett. Over one hundred simulation runs were …

Accounting for Remaining Injected Fracturing Fluid
… of multi-stage fracturing of horizontal wells made the development of shale gas reservoirs become greatly successful during the past decades. A large amount of fracturing fluid, usually from 53,000 bbls to 81,400 bbls, is injected into the reservoir to create the fractures. However, only …

Modeling fluid imbibition for hydraulic fracturing and its implications on unconventional hydrocarbon recovery
The deliverability of a hydraulically fractured well relies on three segments: fluid flow from matrix to the contact surface between fracture and matrix media, fluid-rock-ion interactions at the fracture-matrix interface, and conductivity of fracture network in the created stimulated reservoir …

Challenges of geophysical processes and interpretation of an unconventional play: a case study from Wattenberg field, Denver-Julesburg Basin, Colorado, The
Unconventional production formations are frequently complex to characterize, due to what could be interpreted as sudden lateral stratigraphic changes, potential stress variations, and the inability to use Gassmann's Fluid Substitution theory directly. While general trends of limited permeability, …
