Challenging Diagnostic Fracture Injection Test Compliance Method in the Montney

Challenging Diagnostic Fracture Injection Test Compliance Method in the Montney

Current practice for conducting minifrac or diagnostic fracture injection tests has been changing with time. The Alberta Energy Regulator (AER) has a pressure and deliverability testing directive that has guidance on those tests. This guidance was updated in late 2021. Many operators from the Canadian Montney shale play submit minifracs to AER, 80 of these minifracs were summarized statistically in this presentation. Closure, reservoir pressure, and permeability were the main analyzed parameters in the presentation scope.


Requirements for pressure and deliverability tests are set out by this newly updated directive. Industry uses minifrac in horizontal wells with multistage fracture treatments when developing unconventional reservoirs. Closure, initial reservoir pressure is commonly being determined with the common well test. Closure pressure by Compliance method is challenged in this presentation.
