Unconventional Reservoirs

Wednesday, 22 October
Room 332CF
Technical Session
This session explores the latest advancements in understanding and optimizing oil and gas recovery in unconventional shale reservoirs. Topics include innovative modeling techniques for fractured formations, enhanced oil recovery (EOR) strategies such as CO2 huff-n-puff and cyclic gas injection, and numerical and experimental insights into in-situ combustion performance. Additionally, the session will highlight breakthroughs in formation evaluation methodologies like DFIT-FBA for the Permian Basin, new type curves for reserves estimation, and hybrid simulation models integrating discrete fracture and embedded discrete fracture modeling (DFM & EDFM). By bridging laboratory research with field-scale dynamics, this session provides a comprehensive overview of shale reservoir behavior and optimization strategies for improved hydrocarbon extraction.
