Handling flow through fractured media is critical for transient pressure and flow analysis in shale gas reservoirs, because gas production from such low-permeability formations relies on fractures, from hydraulic fractures and fracture network to various-scaled natural fractures, to provide flow channels for gas flow into producing wells. This study presents a numerical investigation of pressur...

Field observations have shown that interference between wells caused by connected fractures commonly exists in unconventional reservoirs. The well effect and conformance issues could lead to minimal enhanced oil recovery response (EOR) actual operations if they are not properly controlled. A series of data analysis, modeling, experimental activities were performed this study investigate the gas...

Accurate and efficient numerical simulation of unconventional reservoirs is challenging. Long periods transient flow steep potential gradients occur due to the extreme conductivity contrast between matrix fracture. Detailed near-well/near-fracture models are necessary provide sufficient resolution, but they computationally impractical for field cases with multiple fracture stages. Previous work...

Water loss in low permeability reservoirs during hydraulic fracturing well completions typically results in a decrease in natural gas production due to capillary trapping near the fractures. Shale gas reservoirs, however, have shown a trend of improved gas production with increased loss of completion fluids to the shale. This nonintuitive relationship between water imbibition and enhanced gas p...

The premise of this work is the development and application of a new methodology to forecast production data in unconventional reservoirs where variable rate and pressure drop data are typically observed throughout production. Decline curve analysis techniques for the estimation of ultimate recovery (EUR) require the constant bottomhole pressure condition during the producing life of the well —...

The development of effective strategies for hydrocarbon extraction through unconventional shales requires a comprehensive understanding of shale petrophysical properties – specifically the variability of fabric, composition, matrix, porosity, permeability, and thermal maturity/organic content [1-5]. Unconventional resource extraction from shale can involve the injection of carbon dioxide (CO2) ...
