Enhanced recovery

EOR Operations-2014

Enhanced-oil-recovery (EOR) methods have been increasingly positioned into the mainstream of project planning these past years as conventional, highly productive, and large reservoirs have become more difficult to find.

Enhanced-oil-recovery (EOR) methods have been increasingly positioned into the mainstream of project planning these past years as conventional, highly productive, and large reservoirs have become more difficult to find. As a result, in recent years, various innovative EOR techniques seeking to maximize total reservoir recovery have gained renewed interest and attention. However, despite the wealth of knowledge already available and heavy investments made from a number of operators, it is certain that the potential of EOR solutions has not been fully realized.

One key area that can boost EOR projects’ results and challenge the professionals involved is the pursuit of EOR operational excellence. Although it can be seen as a trivial target, it is in fact a quite complex goal. Besides experienced management, it involves a well-prepared multidisciplinary team in the planning phase, definition, controlling of the contracts, and the safe and precise execution and monitoring of the operation. Integration is key to the implementation of efficient and safe operations with minimization of operational costs. Like a winning World Cup football team, victory will depend as much on a good coach as on well-prepared and integrated players. They have different roles to play during the game, but they all target the same goal.

During the past year and the first quarter of 2014, SPE hosted several events focusing on EOR operations and more than 400 papers have been presented. The topic explored in several of them relates the urgency of achieving EOR operational excellence. The papers selected for this month’s feature also validate and confirm the worldwide focus on improving hydrocarbon recovery through efficient and safe EOR operations. I hope you will enjoy reading these paper highlights and will search for additional interesting contributions that are available at the OnePetro online library.
