Development and Application of a Simplified Method for Preliminary Assessment of Enhanced Oil Recovery and CO 2 Geological Storage in Petroleum Reservoirs

Year: 2025

Type: article

Abstract: ABSTRACT Geologic carbon storage in depleted oil and gas reservoirs is a key CO 2 mitigation strategy, utilizing existing infrastructure such as injection wells and pipelines, while capitalizing on well‐characterized subsurface properties. This article introduces a versatile methodology designed to estimate critical parameters, including the number of wells needed for CO 2 storage, recoverable oil volumes, the CO 2 content in produced oil, maximum storage capacity, and additional recovery time. This approach is based on established correlations and literature data, providing a simplified cost‐effective preliminary assessment prior to investing resources (labor and capital) into detailed site‐specific studies, which is particularly advantageous in underexplored or emerging basins. The methodology has been validated against field data for a real mature oil field in Brazil, demonstrating its broad applicability and yielding relatively accurate predictions for key performance indicators. This practical tool facilitates the screening of reservoirs worldwide and supports decision‐making for CO 2 ‐enhanced oil recovery (CO 2 ‐EOR) and long‐term carbon sequestration initiatives. 2025 Society of Chemical Industry and John Wiley & Sons, Ltd.
