Overview

Randomized trial evaluates recovery strategies in carbonate reservoirs, suggesting optimal development practices.

Key Points

  • This research aims to optimize strategies for Improved Oil Recovery (IOR) in heterogeneous carbonate reservoirs.
  • Developed a high-resolution static and dynamic reservoir model with 2.86 million cells using well-log, core, and production data.
  • Conducted multiple simulation scenarios focusing on key parameters like well spacing, injection pattern, and stimulation.
  • Calibrated the model through history matching to assess recovery factors.
  • Natural depletion yields low recovery of 4.5%, whereas optimized water injection and gas lift enhance recovery efficiency.
  • The five-spot injection pattern nearly doubles recovery efficiency compared to linear injection.
  • The optimized scenario results in the highest recovery factor of 14.6% after 30 years.
