We developed a new approach for 4D Close-the-Loop using 4D probabilistic seismic inversion as input for a subsequent 4D Assisted history matching. The probabilistic inversion, using Shell’s proprietary software XStream/Promise, based on the dynamic model combined with the rock model properties, can reveal complex saturation changes and shows their lateral and vertical distribution. The 4D assisted history matching will be using the inverted saturations and fluid contacts to feed into the history match process as additional data. The workflow is successfully tested and applied to several offshore oil-fields and even one gas-field.
