Calsep's expertise also comprises developing a common EOS model valid for multiple reservoir zones in communication and/or fluids coming from different reservoirs.
Development of a single EOS model valid for multiple fluids becomes particularly challenging when miscible gas injection EOR is applied. Since a single EOS model for multiple fluids is typically used in compositional reservoir simulation studies with a high number of grid blocks, a heavily lumped fluid model is often required.
Calsep can include reservoir communication studies in EOS modeling projects for multi-zone reservoirs to reveal whether a single EOS model is needed or the different zones might as well be simulated using different EOS models.
The fluid description may be exported to the most commonly used reservoir simulators, e.g. Eclipse, VIP, More, and Prosper/MBAL.
