Reservoir Management Competency Assessment (RMCA) is a proprietary methodology to quantify subsurface risk. This approach aims to numerically quantify reservoir management's quality and effectiveness using key metrics calculated based on observed data at the field, well, and reservoir levels. A score is assigned automatically based on specific metrics corresponding to each of the five reservoir management categories listed below. Scores generated are benchmarked against the best-managed reservoirs in the world. Each category is equally weighted, with 20 points per category, for a total possible score of 100.
These categories, which represent the principal categories of reservoir management, include the following:
- Production Performance assesses the sustainability of production trends at the field level, rewarding plateau production and penalizing steep declines.
- Pressure Management assesses reservoir pressure management, rewards maintenance, and penalizes pressure declines.
- Water Management assesses the effectiveness of water control, rewarding stable or low water cut increases and efficient waterflooding.
- Gas Management assesses the effectiveness of controlling free gas production, rewarding GOR below solution GOR at the well and field levels.
- Recovery Efficiency benchmarks the recovery factor achievable under the current depletion plan against global standards.
The five components produce a potential score of 100. Scores above 80 are considered very good. From a reservoir perspective, scores below 60 are considered poorly managed. From a reservoir management perspective, RMCA scores between 60 and 80 are considered average.
