Practical Aspects of CO2 Flooding EOR, and CO2 Geosequestration

Reservoir Descriptions and Dynamics


About the course

This course is based on the SPE Monograph Volume 22, ‘Practical Aspects of CO2 Flooding’, published in 2002, and is an outgrowth of The University of Texas of the Permian Basin/ SPE CO2 Conferences and short-courses held in Midland, Texas, every December, for the past several years. The co-authors of the monograph presented a review of the monograph at the December 2002 Conference. The authors’ presentations and the monograph were very well received by the conference attendees, and it is the instructors’ opinion that this course and the monograph should also be very well received by the SPE members outside the Permian Basin area as well. The instructors intend to present this course in conjunction with the SPE conferences/ workshops/ seminars around the world, wherever there is an interest in improving oil recovery from oilfields by CO2 flooding or by hydrocarbon gas flooding, and in CO2 geosequestration, a topic of growing interest to the SPE members around the world. In teaching this course, the instructors plan to: (1) spend most of the time discussing the practical aspects of CO2 flooding, and keep discussion of the theoretical topics to bare minimum, (2) discuss economics of CO2 flooding (vis-à-vis water flooding), (3) give the course attendees some practical and useful problems to work on in the class, (4) discuss CO2 geosequestration wherever there is interest in this topic, and (5) provide each course attendee a course manual containing copies of the instructors’ PowerPoint presentations, and solutions to the class problems.

The course instructors, all seasoned engineers and longstanding members of SPE, offer their extensive experience and expertise in practical aspects of CO2 flooding to teaching this course to the SPE members around the world.

This course was first taught in 2004, in conjunction with the biennial SPE IOR Conference, that is held in Tulsa, and since then, it has been taught there regularly, and will be taught there again in 2018. In addition to Tulsa, this popular course, or an expanded version of it, has been taught in Abu Dhabi, Barcelona, Buenos Aires, Denver, Houston, Jackson, Rio de Janeiro, and San Antonio. As of now, more than 400 SPE members and non-members, around the world, have attended this popular course or an expanded version of it.

Learning Level


Course Length

1 Day

Who Should Attend

Petroleum engineers, reservoir engineers, production engineers, facilities engineers, managers, government officials, and others involved or interested in CO2 flooding or in hydrocarbon gas flooding, for improving oil recovery from oilfields around the world, and in CO2 geosequestration.

Since this topic is of tremendous interest to the SPE members around the world, presentation of this course is expected to attract large attendance; therefore, those who are interested in attending this course should register early. Since Excel programs may be provided in the class, the course registrants should plan to bring their notebook computers to the class.


Attendees of SPE training courses earn 0.8 CEUs for each day of training. We provide each attendee a certificate upon completion of the training course.

In addition to providing strategic direction and leadership to the company, that he founded in 1990 and that now provides full-service, multi-discipline, integrated consulting services to the worldwide oil & gas industry for onshore and offshore (shallow and deep water), conventional and unconventional/shale, oil, gas, gas-condensate/volatile oil, and heavy (and extra heavy) oil field evaluation, development and optimization (to maximize oil & gas recovery and project profitability), he is active in consulting and training in his areas of technical expertise.

Sam Avasthi has over 45 years of worldwide oil & gas industry experience in petroleum engineering, reservoir engineering and simulation/modeling, EOR/IOR project design, evaluation and optimization; revitalizing mature oil fields, and related projects. He has been providing consulting services to the worldwide oil & gas industry since the early 1970s, and has been involved in conducting reservoir engineering and simulation studies of some of the major EOR/IOR projects.

Sam Avasthi has lectured extensively, around the world, on numerous topics in his areas of technical expertise. He is a co-instructor of several popular public training courses taught under the auspicious of the Society of Petroleum Engineers (SPE): ‘Practical Aspects of CO2 Flooding EOR’, ‘Geological Sequestration of CO2’, ‘Practical Aspects of Thermal EOR’, ‘Optimizing Gas Fields using Integrated Asset Modeling (IAM), and Introduction to Optimizing Shale Gas and Tight Oil Fields’, ‘Practical Reservoir Surveillance and Management Techniques for EOR/IOR Projects’, and ‘Practical Techniques for Screening Deepwater Offshore Oil and Gas Exploration Prospects’.

Sam Avasthi is an engineering alumnus of the Indian Institute of Technology (Indian School of Mines), Imperial College London, and Texas A&M University (where he earned a Ph.D. degree in Petroleum Engineering). He was a Research Fellow in Chemical Engineering at Rice University, and worked for several years in senior-level petroleum engineering and consulting positions with major integrated global energy and consulting companies before founding Avasthi & Associates, Inc. in 1990. He is a licensed Professional Engineer (P.E.) in Texas, a Legion of Honor member of SPE, and a Technical Editor of ‘SPE Reservoir Evaluation & Engineering Journal’, ‘SPE Production & Operations Journal’, and the ‘SPE Oil and Gas Facilities Journal’.
