... EOR HnP on shale samples from the Duvernay and Montney. To evaluate how EOR operations could potentially alter the microstructure of unconventional formations, HnP experiments were conducted with a mixture of methane and ethane (C1:C2/72:28mol%) were performed on crushed samples (7-8 mm) from Duvernay...

... in tight reservoirs. A liquid/relative permeameter, previously developed for measuring single/two-phase gas (hydrocarbons/non-hydrocarbons) and liquid (oil, brine) flow in tight rocks, has been modified to perform core-based HNP experiments. The experimental procedure involves: 1) artificially fracturing...
