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.

Phased Pilot Approach Reduces Uncertainty in Carbonate Steamflood Development
The First Eocene is a multibillion-barrel heavy-oil carbonate reservoir in the Wafra field, located in the Partitioned Zone between Saudi Arabia and Kuwait. After more than 60 years of primary production, expected recovery is low and provides a good target for enhanced-oil-recovery processes.
Viability of Gas-Injection EOR in Eagle Ford Shale Reservoirs
This paper studies the technical and economic viability of this EOR technique in Eagle Ford shale reservoirs using natural gas injection, generally after some period of primary depletion, typically through long, hydraulically fractured horizontal-reach wells.
Experimental Program Investigates Miscible CO2 WAG Injection in Carbonate Reservoirs
This paper provides a robust methodology for miscible CO2 WAG experimental-data acquisition and history matching.
