Accurate Calculation of Coning Behavior in Full Scale Reservoir Models

摘要

In many cases water-and gas coning are responsible for early water or gas breakthrough and for a high watercut and GOR, leading to rapid decrease of the oil Production rate. Unfortunately most of the Conventional simulators are unable to pre- Dict this phenomenon with sufficient precisi- On. Beyond this the calculated bottom hole Pressures are far away from the real values. The reason is that he commonly used anlay- Tical well models (such as the Peaceman mo- Del, [5]) are not valid for multi phase flow And do not provide the necessary resolution For the near wellbore area.
