Diagnostic Fracture Injection Tests Analysis and Numerical Simulation in Montney Shale Formation

Unconventional oil and gas formations are abundant, have become an increasingly important part of the global energy supply, attracting increasing attention from industry. Predicting key reservoir properties plays a significant role in both geological science subsurface engineering workflows. With advent horizontal well drilling multiple-stage hydraulic fracturing, Montney Shale formation is one most promising productive shale Canada. However, very few academic papers discuss its situ stress, pressure, permeability, which essential for development Shale. The objective this study to analyze geo-stress, pore several by using diagnostic fracture injection test (DFIT) data One Wapiti field has been analyzed with set DFIT data, results show that general pressure Gdp/dG responses Well-A indicate signature height recession/transverse storage. In study, Tangent Line method, Compliance Variable method applied estimate properties. As result, analysis estimates closure ranging 34.367 39.344 MPa, contributing stress gradient 14.09 16.13 KPa/m formation. 20.82 24.58 8.54 10.07 porosity 3% 6%. These contoured cross Using DFIT’s numerical simulation history matching, permeability 0.024 md, length 13.44 m, geometries different models. Moreover, physics behind discussed detail. For first time, three methods series case wells This approach can not only reduce potential prediction error caused single application but also increase persuasiveness assessment save ensuring efficient implementation operations. Given significance quantifying unconventional hydrocarbon exploration development, could help operator quickly understand regimes, geometry, field. Furthermore, interpreted demonstrated paper adding substantial business value asset, especially terms improving fracturing design and, thus, accelerating cashflow production.
