Using object-oriented concepts to define grids has greatly enhanced flexibility in the data structure needed to support a number of different and important capabilities. Such capabilities include simulations of multiple, coupled reservoirs, unstructured grids of the PEBI type, and parallelization at different levels of granularity. These beneficial capabilities have been realized by new software without sacrificing efficiency. In fact, the formulation is highly efficient and benchmarks consistently indicate significantly improved performance over currently offered commercial reservoir simulators used for conventional simulation of individual reservoir systems. In this sense, the Nexus approach is scalable. For example, it maintains efficiency for simple problems, as well as for more complex problems involving multiple reservoirs and surface networks. Additionally, the software's enhanced performance enables the simultaneous solution of multiple reservoirs sharing a common surface facility. © 2008 EAGE.
