Integrated Asset Modeling for Deep Gas Reservoirs. Case Study in UAE

Abstract

The primary objective of reservoir management is the maximization of plateau duration and reserves recovery, while minimizing the project risks and maintaining the highest environmental and safety standards. It is critical to identify upfront all the risks and bottlenecks that may occur through the entire life of the assets, to prevent them from happening or minimize the reaction time in case of occurrence. Integration of all asset elements (subsurface dynamic models and a surface facility network) provides a fit-for-purpose tool to optimize assets development. This article describes fully coupled surface and subsurface modeling done for 6 reservoir formations (3 fields) sharing the surface facility and including 6 gas reservoirs with different PVT properties. A fully integrated model describes all technical processes occurring in the subsurface and surface systems and has to be further calibrated using measurements done as per the reservoir monitoring plan.
