Enhanced Oil Recovery (EOR) technologies can significantly increase recovery from oil reservoirs.Some of these EOR technologies are currently producing substantial incremental oil, primarily in onshore applications; others have not yet made a commercial impact. The application of these methods is more complex in the offshore environment, as space and weight restrictions, as well as the need for high reliability and the challenging economics of such projects, impose constraints not present in onshore applications.All EOR processes are reservoir- and reservoir fluid-specific; thus it is necessary to identify the appropriate EOR technology for use in a reservoir, design the project to achieve the required economic incremental recovery within the constraints imposed by the offshore environment, and manage the project to meet or exceed expectations.

This paper will focus on the impact of the offshore environment on the planning, design and management of an EOR project.
