SPE Forum: Is Cyclic Gas Injection EOR the Future for Unconventional Resources

The Society of Petroleum Engineers (SPE) and the SPE Forum Series is excited to announce this forum will be virtual! The forum will occur in a ..

The potential for technology to increase the productivity of unconventional resources (UCR) has seen a considerable boost following the application of cyclic gas injection projects in the Eagle Ford shale play. However, significant challenges remain to apply these learnings successfully to other reservoirs. UCR typically includes highly-heterogeneous and fractured reservoirs which pose unique challenges related to reservoir containment both horizontally and vertically, and hydrocarbon contact (micro and macro-sweep efficiency). Despite these challenges, this cyclic gas injection has been shown to enhance oil recovery above primary depletion in the Eagle Ford. This potential has led to many operators pursuing their own in-house process of de-risking and pilot development in other fields with a goal to learn from others and establish best practices.
