Carbon Dioxide Enhanced Oil Recovery Injection Operations Technologies (Poster Presentation)

Abstract

Over the past 35 years, the oil and gas industry has developed many technology improvements and operating practices for injecting carbon dioxide (CO2) for enhanced oil recovery (EOR). Over this time, the US oil and gas industry has operated over 13,000 CO2 EOR wells, over 3,500 miles of high pressure CO2 pipelines and has injected over 600 million tons of CO2 without any significant safety or environmental endangerment events. Today, the US produces over 245,000 barrels of oil per day as a direct result of CO2 EOR. This presentation will describe many of the technical improvements and operational practices that have been developed as a result of the oil and gas industry's experiences with CO 2 EOR. When these technologies and practices are applied, operators can expect facility and wellbore integrity at levels equivalent to those seen for conventional oil an d gas operations. Many of the technologies and practices that have been developed for CO2 EOR may have applicability in carbon capture and storage (CCS) projects, recognizing however, that each project should be designed to meet its site specific conditio ns. The CO2 EOR experiences of the oil and gas industry represent the largest collective base of technical information available on CO2 injection and, as such, provide valuable information for development and implementation of CCS field projects as they move forward. © 2009 Elsevier Ltd.
