In the ResX objective function 4D seismic data is represented as a 2D surface. Multiple surfaces can be included, for example one per extraction window and per time-lapse interval. When used in an ensemble-based study, the output of the 4D workflow is an ensemble of reservoir models that are consistent with static, production and 4D seismic data, while capturing uncertainty. This leads to better decision-making for assets employing 4D seismic data. Putting you in a better position to increase higher ultimate recovery.
The ability to select the response to be used offers the ability for the users to adopt the matching data best adapted to the project’s objectives. Likewise, the choice of domain offers flexibility. For example, it is generally quicker to move an interpretation of measured data into the simulation space to make comparisons there, but if time and resources are available, simulator results can be processed and made available for comparison in the seismic domain.
