Smart well zonal allocation

PRODML WG 2007

The Problem To run smart wells at its optimum level it must be

possible to determine the zonal reservoir pressure at any time and compare those with the theoretical expected pressure calculated from your well and network models. A comparison of the theoretical value with the actual calculated value is a key performance indicator if the well/reservoir behaved as expected. If not the system needs to be recalibrated.
