Abstract
Field application of cyclic gas injection (CGI) has proven to increase rates and recovery factors in Eagle Ford. However, depsite years of experience in conventional reservoirs, a comprehensive understanding of the factors that yield to a successful CGI project in unconventional play is yet to be developed. Because a hydraulically created fracture system controls the flow while the fluid is stored in ultra-tight, nanoporous matrix, integrated understanding of the physics of the unconventional reservoir, the fluid system, exchange between matrix and fracture media, and the dynamic nature of the hydraulic fracture properties is essential for the successful design and implementation of CGI in unconventionals. This presentation focuses on the unconventional aspects of CGI and demonstrates utilization of modeling solutions to understand the reservoir, design a successful gas injection project, and quantify its success. The key take aways of the presentation are the success factors of CGI projects, importance of containment of gas and contact of gas with oil, and the impact of timing on the economic viability of implementation.
