| Sustainable Oil Industry Development With Carbon-Constrained Economy in Saudi Arabia Hussein Hoteit1; 1KING ABDULLAH UNIVERSITY OF SCIENCE & TECHNOLOGY (KAUST), Thuwal, Saudi Arabia; PAPER: 156/Energy/Regular (Oral) SCHEDULED: 12:20/Tue. 29 Nov. 2022/Game ABSTRACT: The ongoing accumulation of greenhouse gas (GHG) concentrations in the atmosphere from various anthropogenic sources is believed to be the primary cause of the increasing earth's surface temperature. CO2 is the most significant GHG where the top anthropogenic sources of CO2 emissions are related to electricity generation and stationery industry sectors powered by fossil fuels. Among other technologies, carbon capture, utilization, and storage (CCUS) is expected to play a key role in addressing the GHG emission challenges. Since the early days of the oil and gas industry, CO2 injection in oilfields has been recognized to be an effective method for enhanced oil recovery (EOR). However, the worldwide CO2-EOR implementations remain modest. In this talk, the 50-year history of CO2-EOR is reviewed, where we highlight the key attributes of successes and failures. The recovery benefits and the challenges of CO2-EOR in relation to CO2 capture, transportation, and oil displacement in the subsurface are discussed. We then show, for the first time, a comprehensive map of the current CO2 emissions from stationary industrial sources in Saudi Arabia. We discuss the potential of CO2-EOR in Saudi Arabia and provide an estimate of CO2 storage in depleted hydrocarbon fields, as well as other geological formations, including deep aquifers and CO2 mineralization in basalts. We close with some thoughts regarding the role of the oil and gas industry in Saudi Arabia in capitalizing on this opportunity by promoting CCUS as a win-win technology. |
