CO 2 Capturing and Storage From Oil Wells

Abstract

The world is currently facing one of the most critical challenges in the Earth’s history which is global warming. The major cause of global warming and climate change problems is the carbon dioxide emissions. This novel study addresses the concepts and design precautions for a proposed in-situ electricity generation project. The main goal of the study is to reduce the environmental pollution due to the combustion of fossil fuels and emitting carbon dioxide. This reduction will be attained through a smart gas well design and completions. The design is based on in-situ combustion for a gas flow in a downhole combustion chamber. Oxy-fuel combustion technique is the proposed combustion technique due to the ease of CO2 separation in this process. The proper well design will be analogous to the wells used for in-situ oil combustion to handle the high released temperature. Power generation design will combine the fundamentals of geothermal energy deployment for electricity generation. Finally, the produced CO2 from the combustion process will be reinjected downhole into an underground geological structure after being compressed and transferred to the supercritical phase. This process eliminates the CO2 production to the surface and hence reduce the environmental pollution.
