... in this paper. It was seen that depletion around fractures can likely be identified using drilling data and this can sometimes be further validated by changes in the mud gas composition. It will demonstrate how some fractures have depletion associated with them, while others do not, and may provide insight...

CO 2 HNP processes have been studied experimentally for organic-rich shale reservoirs (often using crushed-rock samples), very few studies have compared EOR performance of CO 2 and lean gas (with variable compositions) under realistic subsurface conditions. The objectives of this work are therefore...
