Utilization of CO2 for enhanced oil recovery (EOR) and sequestration processes not only reduces greenhouse emissions, but also awards economic benefits. Enhancing oil recovery using sequestration is an optimization process that requires careful analysis. In CO2 EOR, the main purpose is to maximize oil recovery using the minimum quantity of CO2 while at the same time, sequestering the maximum amount of CO2 in the field. The Kartaltepe Field, having 32 degrees API gravity oil in a carbonate formation, in southeast Turkey has been considered in this study. Reservoir rock and fluid data were evaluated and merged into CMG's STARS simulator. A history matching study was done with production data to verify the results of the simulator with field data. From the results of the simulation runs, it was realized that CO2 injection can be applied to increase oil recovery, but sequestering high amounts of CO2 was found out to be inappropriate for the Kartaltepe Field. Therefore, it was decided to focus on oil recovery while CO2 was sequestered within the reservoir. Oil recovery was about 23% of OOIP for the field in 2006. It reached 43% of OOIP by injecting CO2 after properly defining production and injection scenarios.

A Numerical Simulation Study of Carbon-Dioxide Sequestration into a Depleted Oil Reservoir Pamukcu, Y. Z.; Gumrah, F. (Informa UK Limited, 2009-01-01) Utilization of CO2 for enhanced oil recovery and sequestration processes not only reduces greenhouse emissions but also awards economical benefits. Enhancing oil recovery in a sequestration is an optimization process that requires careful analysis. In CO2-enhanced oil recovery the main purpose is to maximize oil recovery with the minimum quantity of CO2 while a maximum amount of CO2 is aimed to store in a sequestration. Kartaltepe field having 32 degrees API gravity oil in a carbonate formation from southea...
Simulating the effects of deep saline aquifer properties for CO2 sequestration Basbug, B.; Gumrah, F.; Oz, B. (2007-10-01) CO2 is one of the hazardous greenhouse gases causing significant changes to the environment. The sequestering of CO2 in a suitable geological media can be a feasible method to avoid the negative effects of CO2 emissions into the atmosphere. A numerical model was developed regarding CO2 sequestration in a deep saline aquifer. A compositional numerical model using CMG software (GEM) was employed to study the ability of the selected aquifer to accept and retain large quantities of CO2 injected in a supercritic...
The Evaluation of an Immiscible-CO2 Enhanced Oil Recovery Technique for Heavy Crude Oil Reservoirs Kök, Mustafa Verşan (Informa UK Limited, 2012-03-01) Sequestration of CO2 in enhanced oil recovery applications has been widely recognized as one of the favorite techniques for reducing emissions of CO2 into the atmosphere in response to global climate change. This technique provides lower costs for CO2 sequestration by means of higher incremental oil recoveries. There are some key parameters, when considering a.field for the CO2 displacement. Oil reservoirs are screened out according to oil gravity, reservoir temperature and pressure, minimum miscibility pre...
Simulating oil recovery during CO2 sequestration into a mature oil reservoir Pamukçu, Yusuf Ziya; Gümrah, Fevzi; Department of Petroleum and Natural Gas Engineering (2006) The continuous rising of anthropogenic emission into the atmosphere as a consequence of industrial growth is becoming uncontrollable, which causes heating up the atmosphere and changes in global climate. Therefore, CO2 emission becomes a big problem and key issue in environmental concerns. There are several options discussed for reducing the amount of CO2 emitted into the atmosphere. CO2 sequestration is one of these options, which involves the capture of CO2 from hydrocarbon emission sources, e.g. power pl...
Simulating CO2 sequestration in a depleted gas reservoir Özkılıç, Öke İsmet; Gümrah, Fevzi; Department of Petroleum and Natural Gas Engineering (2005) Carbon dioxide is one of the greenhouse gases which have strong impacts on the environment and its amount in the atmosphere is far beyond to be ignored. Carbon dioxide levels are projected to be reduced by sequestering it directly to the underground. High amounts of carbon dioxide can be safely stored in underground media for very long time periods. Storage in depleted gas reservoirs provides an option for sequestering carbon dioxide. In 2002, production of Kuzey Marmara gas reservoir has been stopped due t...
