Reservoir simulation
From Wikipedia, the free encyclopedia
Reservoir simulation is an area of reservoir engineering in which computer models are used to predict the flow of fluids (typically, oil, water, and gas) through porous media.

[edit] Uses
Reservoir simulation models are predominantly used by major oil and gas companies in the development of new oil fields. As building and maintaining robust, reliable models of fields is often time-consuming and expensive, models are typically only constructed where large investment decisions are at stake.
[edit] Types
Traditional finite difference simulators dominate both theoretical and practical work in reservoir simulation. Finite difference models come in both structured and more complicated unstructured grids, as well as a variety of different fluid formulations, including black oil and compositional.
Other types of simulators include finite element and streamline.
[edit] Applications
Several reservoir simulators have been written over the years. Vendor software includes (alphabetically):
- ECLIPSE, by GeoQuest, a division of Schlumberger
- Sensor, by Coats Engineering, with original funding from Phillips Petroleum Company (now ConocoPhillips)
- STARS, by Computer Modeling Group
- SURE, by SMT
- Tempest, by Roxar
- VIP® and Nexus®, by Landmark, a division of Halliburton
So-called "in-house" packages have been developed by several major oil and gas companies, including (again, alphabetically):
- CHEARS, by Chevron
- EMpower, by ExxonMobil
- MoReS, by Royal Dutch Shell
- POWERS, by Saudi Aramco
