Perspectives of CO₂ Injection Strategies for Enhanced Oil Recovery and Storage in Indian Oilfields

Abstract

The motivation behind the advancement of novel technologies for enhanced oil recovery (EOR) originates from the increasing energy demand and imperative to explore new oil reserves. Novel approaches, including the injection of carbon dioxide (CO 2 ) and sequestration of CO 2 in oil reservoirs, have emerged as potential remedies. In response to the rising apprehensions regarding global warming attributed to anthropogenic activities and the consequent rise in CO 2 emissions, scholars are directing their attention toward the utilization of CO 2 sequestration methods for EOR. This methodology presents an achievable strategy to reduce anthropogenic CO 2 emissions and diminish their influence on the atmosphere. The implementation of CO 2 sequestration in EOR operations has the potential to yield the dual benefits of cost reduction and additional oil recovery. The paper presents a study that investigates distinct scenarios of CO 2 injection and sequestration in various formations. The study incorporates conventional methodologies, such as gas injection, for the purpose of EOR. It explores diverse fields of CO 2 injection and sequestration, deliberates on the decision-making process concerning injection strategies, and employs dynamic as well as static models to generate long-term production profiles, evaluate production profiles, and manage the process. The paper explores the challenges encountered by various industries in the process of capturing, transporting, and storing of CO 2 in geological formations. Additionally, the study assesses the geological potential and practicality of implementing this methodology in India. In brief, this study presents a thorough examination of Indian scenarios for CO 2 injection and sequestration utilized in EOR techniques.
