本研究は、エジプトのObaiyed油田におけるCO2地中貯留の技術経済分析を実施。ガス処理プラントからの純粋なCO2を対象に、地表設備と坑井の評価、費用便益分析を行った。その結果、凝縮油回収を前提とすると内部収益率100%、NPV 4.03億ドル、回収期間1年と高い経済性を示した。また、炭素価格の導入や炭素クレジット取引により、凝縮油回収なしでも事業が成立する可能性を明らかにした。
English
This study conducts a techno-economic analysis of geological CO2 storage at the Obaiyed oil field in Egypt, focusing on a pure CO2 source from a gas processing plant. Evaluating surface facilities and wells, cost-benefit analysis shows a high internal rate of return (100%), NPV of $403 million, and payback period of 1 year with condensate recovery. Sensitivity analysis reveals that carbon pricing and trading carbon credits can fully finance the project even without condensate recovery.

📄 Abstract（原文）
Carbon capture and storage (CCS) is promoted as a promising decarbonization strategy. It is argued to be a potential solution for Egypt’s greenhouse gas emissions, which have substantially grown over the past three decades. A widely recognized CCS method is carbon geological storage in petroleum reservoirs. However, there is a remarkable lack of research on CO2 conditioning and transport in oil fields. This research aims to assess the storage of a pure source of CO2 emitted from a gas process plant in Obaiyed oilfield in Egypt. To do so, this paper performed a systematic review of the available surface facilities and well assets at Obaiyed and made a cost-benefit analysis. The findings showed that assuming 3333 barrels/day condensate recovery from injection, the project would yield an internal rate of return of 100%, a net present value (NPV) of $403 million, and a payback period of 1 year. A sensitivity analysis found that the NPV increases sharply with an increase in oil prices and the adoption of carbon pricing. Trading carbon storage credits in the Egyptian carbon market is found to be capable of entirely financing the project, even without any condensate recovered. Since most of the research in this area focuses on subsurface investigation, the novelty of this paper comes from its interdisciplinary approach by combining surface and well analysis and financial estimation, reflecting the very local context in Egypt.
