Abstract
The 4D ROVER (Remaining Oil Volume Estimation And Redistribution) project aimed to provide a quantitative measure of remaining oil in the oil rim from the Troll West field, by deploying the Shell proprietary probabilistic layer-based inversion tool to the license partners. Due to structural complexity of the static model, the three reservoir fluids and a complicated 4D signal, a stepwise inversion approach proved most successful, solving for the most uncertain reservoir parameters first.
