Please join us as Dr. Tuba Firincioglu presents her paper on "Success and Failure Factors for Cyclic Gas Injection in Unconventional Reservoirs". In this session Dr. Firincioglu will discuss success factors of CGI projects, the importance of containment of gas and contact of gas with oil, and the impact of timing on the economic viability of implementation.

This will be hybrid meeting where we will meet at the City Club and Dr. Firincioglu will present remote. There will be an opportunity for Q&A at the end of the session.


Field application of cyclic gas injection (CGI) has proven to increase rates and recovery factors in Eagle Ford. However, despite years of experience in conventional reservoirs, a comprehensive understanding of the factors that yield to a successful CGI project in unconventional plays is yet to be developed. Because a hydraulically created fracture system controls the flow while the fluid is stored in ultra-tight, nano-porous 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 unconventional reservoirs. 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.


Dr. Tuba Firincioglu is the Managing Director at NITEC LLC.  Since joining NITEC as a Reservoir Engineer, she has focused on the application of reservoir engineering technologies for the resolution of complex reservoir development programs. She has performed or managed over 150 reservoir studies involving dry gas, gas condensate, volatile oil, and black oil fields: including modeling and design of many conventional and unconventional EOR applications. Her experience covers most geological depositional environments from fluvial sands to carbonates.

Dr. Firincioglu is an expert in numerical simulation of fractured reservoirs and hydrocarbon phase behavior under confinement.   She has been involved in unconventional oil and gas resource plays since 2009 and has worked on all the major unconventional basins in North America.  During this period, she also designed and taught Unconventional Reservoir numerical simulation courses.

Dr. Firincioglu has served in technical committees of various SPE Conferences and has chaired sessions.    She currently serves in the SPE Reservoir Advisory Committee. She is also the recipient of 2020 Rocky Mountain Regional Reservoir Description and Dynamics Award. 

Dr. Firincioglu holds a B.S. degree from Istanbul Technical University, an M.S. degree from Stanford University, and a Ph.D. degree from Colorado School of Mines, all in Petroleum Engineering.
