The presentation will focus on the rejuvenation of mature oil and gas fields, exploring innovative techniques and strategies to extend their productive life. Topics include incentivization of operators to continue investment in mature fields while understanding the drivers for the investment decisions and choices made, explore the concepts of infrastructure lead exploration and development, enhanced oil recovery (EOR) methods, and adoptions of simplified and fit for purpose engineering standards. Additionally, the presentation will address the importance of sustainability and environmental considerations, such as carbon capture and storage (CCS) technologies. The goal is to demonstrate how these approaches can unlock the remaining potential of mature fields, ensuring continued production and maximizing economic value while minimizing environmental impact.
