Complementary Workflows for Analyzing Multiphase Flowback and Post-flowback Production Data In Unconventional Reservoirs
DownloadFall 2017
The application of horizontal drilling and hydraulic fracturing techniques has resulted in the economic production of previously inaccessible hydrocarbon trapped in very-low permeability reservoirs such as Shale gas/oil, tight gas and tight oil. Although the economic production of these...

Modeling of Recovery and In-situ Distribution of Fracturing Fluid in Shale Gas Reservoirs Due to Fracture Closure, Proppant Distribution and Gravity Segregation
DownloadSpring 2017
Many stimulated shale gas wells experience surprisingly low fracturing fluid recoveries. Fracture closure, gravity segregation, fracture tortuosity, proppant distribution, drawdown pressure and shut-in (soaking) duration have been widely postulated to be the contributing factors. Despite propped...

Numerical Simulation of Shale Gas Production and Fracturing Fluid Distribution: Integration of Apparent Permeability and Secondary Fracture Network Modeling
DownloadFall 2019
Complex flow mechanisms are encountered in shale matrix due to the presence of nanopores. Numerous apparent permeability models have been proposed to capture the ensuing non-Darcy flow behavior. However, these models are not readily available in most commercial reservoir simulators, and ignoring...
