Abstract
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.
