Advanced Parallelization Techniques to Optimize
& Boost Simulator & Hardware Performance


In recent years, reservoirs and recovery methods have increased in complexity and model size, resulting in an increase in simulation computational time. As more company projects integrate reservoir simulation in the decision making process, there is a heavier burden on IT infrastructure which can lead to simulation backlog. As a result, companies often find themselves juggling simulation jobs in order to make decisions on their numerous projects, which inevitably decreases efficiency.

Through significant developments and improvements to multi-core processing technology over the past several years, parallel processing technology solves these challenges, and is rapidly becoming the preferred way to run reservoir simulations. By using multiple processors simultaneously, simulation run-times are much faster and software and hardware usage is optimized, leading to shorter project turnaround time.

The presentation discussed several advanced parallel processing techniques and innovative hardware and software architectures that can be applied to boost the performance of both the simulator and computer. The following main points were covered:

  • Advantages and applicability of this technology to reservoir simulation models
  • CMG's parallel processing technology and the associated keywords
  • Techniques to effectively utilize all available cores with optimized load balancing
  • Case studies showcasing simulator performance speed-up using parallel partitioning
  • CMG hardware and operating system recommendations
