f Stochastic Moment Equations for Uncertainty Assessment of Reservoir Performance Predictions

Reservoir management decisions are often based on performance predictions obtained from<br>numerical flow simulation. The reliability of such predictions depends on the quality and<br>quantity of available information, and then it depends on the ability to capture the physics of<br>flow processes accurately. Unfortunately, only limited information on reservoir properties of<br>varying quality and from different sources is usually available. Thus, a major element of risk<br>is due to incomplete knowledge of the reservoir description, which leads to uncertainty in the<br>obtained flow responses for the displacement processes under investigation.
