Measuring permeabilities of Middle-Bakken samples using three different methods

Because of the high uncertainty in measuring the permeability of tight rock, it is worthwhile to investigate permeability through different methods in order to reduce uncertainty. In this study, we measured the permeability of tight rocks utilizing three different methods with the same setup. The investigated methods were the oscillating pulse method, the downstream pressure buildup method, and the radius-of-investigation method. In this way, the comparison provides uncertainty and magnitude and indicates the possible presence of heterogeneities and lamination.
