Integrating Data to Assess Remaining Recovery Potential
Further analysis can help determine the appropriate mature field optimization methods. Below, we highlight three of the many ways that integrating relevant subsurface data, and collaboratively evaluating it, facilitates mature field production optimization.
1. Efficiently Evaluate Opportunities for Production Optimization
- Compare wells with similar geologic characteristics but different production metrics to isolate factors affecting performance.
- Visualize geologically complex reservoirs in 3D to determine the feasibility of drilling and recovering residual hydrocarbons (attic oil).
- Diagnose downhole pressure issues, to determine why pressure doesn’t match production volumes in a specific well. Is the reason associated with problems in cement, safety valves, tubulars, or artificial lift equipment? Or due to interference with a nearby well?
- Correlate permeability with oil viscosity and recommend alternative tertiary recovery strategy.
2. Identify Bypassed Pay
3. Optimal Infill Drilling Strategy
Case Study: Mature Field Production Optimization
- Identify and capture bypassed oil with a tight-radius horizontal well.
- Determine the optimal wellpaths and drilling techniques using updated geologic models.
- Optimize the steamflood strategy by replacing vertical wells with carefully located horizontal wells.
The ability to easily integrate relevant data and collaboratively analyze it gives reservoir engineers a better understanding of current reservoir characteristics and remaining reserves.
