The MEPO multiple realization optimizer represents a step change in the reservoir engineering workflow. It substantially enhances the value you will get from your existing reservoir simulation models, by enabling a multiple realization approach—allowing you to not only model your reservoir, but also to optimize it for maximum performance.

MEPO software improves your reservoir decisions in a number of areas, including determining the best locations for infill wells, selecting optimal development scenarios, understanding uncertainty, and semi-automating laborious tasks such as history matching. Vitally, the software works in harmony with your existing reservoir simulator, and is easy to understand and use.

Multiple model realization approach

Using modern optimization and experimental design techniques, MEPO software allows you to better explore the solution space of your problem. It also facilitates the use of the multiple model realization approach when facing key decision gates.

MEPO workflows now extend back to your geomodel using the MEPO Link plug-in for the Petrel platform. This enables you to include static model parameters—such as fault positions as history matching parameters—and gives you greater options in optimizing well location. 

Managing uncertainty in simulations

MEPO software enables you to make better decisions by improving work processes and managing uncertainties in your simulation projects. This allows you to

  • understand uncertainties and mitigate risk
  • optimize development plans, production strategies, well targets, etc
  • enhance your reservoir understanding, cost efficiently.

The software also improves communication and collaboration across asset teams, providing

  • enhance understanding of field dynamics by sharing, analyzing and visualizing results
  • conduct integrated modeling with geo tools and production networks.
