EOR For Unconventional Reservoirs
EOR in low permeability unconventional reservoirs is happening across a number of basins and is rapidly becoming a sub-discipline of petroleum engineering. This class covers what has been done over the last decade with a special focus on huff-n-puff (cyclic) gas injection. This includes how to predict production forecasts and injection volumes required, as well as determining the contribution of different recovery mechanisms. Other techniques such as continuous injection and water/surfactant injection are also considered. We examine field trials across all of the basins and discuss the successes and lessons learned from them. Operational aspects to successfully implement EOR in unconventional wells is also covered.
