A Numerical Simulation Study of Carbon-Dioxide Sequestration into a Depleted Oil Reservoir

Pamukcu, Y. Z.

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 southeast Turkey has been considered in this study. Reservoir rock and fluid data were evaluated and merged into CMG/STARS simulator. History matching study was done with production data to verify the results of the simulator with field data. From the results of simulation runs, it was realized that CO2 injection can be applied to increase oil recovery, but sequestering of a high amount of CO2 was found to be inappropriate for Kartaltepe field. Therefore, it was decided to focus on oil recovery while CO2 was sequestered within the reservoir. Oil recovery was about 23% of original oil in place in 2006 for the field, it reached to 43% of original oil in place by injecting CO2 after defining production and injection scenarios properly.


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...
Modeling of CO2 storage in an oil reservoir
Gumrah, F.; Dulger, M.; Gunaydin, D.; Senel, O. (Informa UK Limited, 2008-01-01)
This study provides an overview for the carbon dioxide sequestration process in an oil reservoir by using the software CMG's GEM. Different scenarios are applied for the oil reservoir description. Firstly, a single layered reservoir is considered and simulation studies are performed, as this reservoir is homogeneous, heterogeneous and fractured. Secondly, a multi-layered reservoir is examined. In the second case, a heterogeneous system and a heterogeneous system composed of homogenous layers are selected. F...
An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies
Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01)
The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the ...
Modeling binary CO2/CH4 flow through coal media
Gumrah, F.; Balan, H. O.; Atay, M. U. (Informa UK Limited, 2008-01-01)
CO2 can be sequestered in coal seams considering the environmental issues. By means of injecting CO2 into the coal seams, both sequestration of CO2 and the enhanced recovery of methane inside the coal seam can be realized. One-dimensional simulation regarding the binary CO2/CH4 flow in a coal seam core was studied by using an analytical solution method. The simulation results were compared with experimental data by matching the effluent concentrations of CO2 and CH4. The transport parameters such as longitu...
Parametric Study of Carbon Dioxide Sequestration in Deep Saline Aquifers
Basbug, B.; Gumrah, F. (Informa UK Limited, 2009-01-01)
CO2 sequestration in a deep saline aquifer was simulated using a compositional commercial simulator based on a single-well aquifer model, which was developed to analyze the injection and storage process of CO2 under supercritical and gaseous conditions for long periods of time. The influence of controlling parameters including vertical to horizontal permeability ratio, aquifer pressure, injection rate on the isothermal injection, and sequestration processes were investigated and the sensitivity analysis cor...
