The combination of carbon dioxide enhanced oil recovery (CO2-EOR) and permanent CO2 storage in mature oil reservoirs has the potential to provide a critical near-term solution for reducing greenhouse gas (GHG) emissions. This solution involves the combined application of carbon capture and storage from power generation and other industrial facilities with CO2-EOR. In order to reduce CO2 capture costs flue gas, which consists mainly of N-2 and CO2, injection has been proposed. The main aim of this research is to investigate flue gas injection in a mature oil field located in Turkey where CO2 EOR had been applied between 2003 and 2012. Injected CO2 was produced from a nearby small natural CO2 reservoir with limited resource. Due to the availability of nearby flue gas source (cement factory) and a pipeline for gas transportation, which was built to transport natural gas from the oil field to cement factory, there is a huge opportunity to decrease project costs. A 3D compositional simulation model was built after a detailed fluid characterization. After history matching 31 years of production, injection, saturation and pressure history, a comparative study was conducted to examine the efficiency of flue gas injection compared to CO2 injection for simultaneous EOR and storage purposes. Storage capacity of the oil field as well as the contribution of raw flue gas injection and CO2 injection to oil recovery were studied. Effect of injected gas type, gas solubility and operating parameters on storage and recovery were investigated. Results showed that pure CO2 injection leads to higher oil recovery and CO2 storage, if injection continued for at least 25 years. Before this threshold injection time, flue gas injection and pure CO2 injection resulted in comparable oil recoveries. It was also concluded that pressurizing the reservoir with raw flue gas injection followed by pure CO2 injection may improve the project economics.

Analysis of carbon dioxide sequestration in shale gas reservoirs by using experimental adsorption data and adsorption models
Merey, Sukru; Sınayuç, Çağlar (2016-11-01)
For carbon dioxide (CO2) sequestration in depleted shale gas reservoirs or CO2 injection as an enhanced shale gas recovery technique, it is important to understand the adsorption mechanism in these reservoirs. In this study, experimental adsorption measurements for Dadas shale samples were conducted at 25 degrees C, 50 degrees C, and 75 degrees C up to approximately 2000 psia by using pure CO2 (maximum adsorption capacity 0.211 mmol/g at 25 degrees C) and pure methane (CH4) (maximum adsorption capacity 0.04...
Optimization of CO₂ EOR and storage design under uncertainity
Bender, Serdar; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2016)
The combination of CO₂ enhanced oil recovery (EOR) and permanent CO₂ storage in mature oil reservoirs have the potential to provide a critical near-term solution for reducing greenhouse gas emissions. In the literature, although there are many studies about CO₂ storage and EOR, only a few studies have focused on maximizing both the oil recovery and the CO₂ storage. Moreover, these studies are either experimental or conducted using synthetic reservoir models. Typically, pure CO₂ has the property of mixing wi...
CO2 mitigation from the flue gas of the iron steel making industry by microalgal cultures
Çaylı, Direniş; Bayramoğlu, Tuba Hande; Demirer, Göksel Niyazi; Uludağ Demirer, Sibel (null; 2015-06-15)
Integration of CO2 mitigation with nutrient removal from different wastewater sources can be realized by microalgae growth. In spite of being an option with significant environmental benefits, this technology still suffers from achieving high performances since atmospheric concentration of CO2 limits microalgae growth; i.e. biomass accumulation. This is why the use of flue gas with CO2 concentrations of 20-25% (by volume) should be considered as an inorganic C source for the microalgae culture reactors. Thi...

Capturing and storing carbon dioxide (CO2) underground for thousands of years is one way to reduce atmospheric greenhouse gases, often associated with global warming. Leakage of CO2 through wells is one of the major concerns when storing CO2 in depleted oil and gas reservoirs. CO2-injection candidates could be new wells, or old wells that are active, closed or abandoned. To prevent the leakage, the possible leakage paths and the mechanisms triggering these paths must be examined and identified. It is known ...
CO2 injection in carbonates
Izgec, O.; Demiral, B.; Bertin, H.; Akın, Serhat (2005-07-28)
Started as an EOR technique to produce oil, injection of carbon dioxide which is essentially a greenhouse gas is becoming more and more important. Although there are a number of mathematical modeling studies, experimental studies are limited and most studies focus on injection into sandstone reservoirs as opposed to carbonate ones. This study presents the results of computerized tomography (CT) monitored laboratory experiments to characterize relevant chemical reactions associated with injection and storage...
