Abstract

Geoscreening is a process which links the static and dynamic components of a subsurface model together to allow the system to be studied as a whole. It allows the range of possible geological models to be refined to those that also satisfy the dynamic data. This provides us with an improved understanding of the nature of the static and dynamic relationship; improved HM time and reduces the need for RE patches; and improved development plans by linking static and dynamic processes. The static geological model underlying the dynamic reservoir engineering model is the primary control of the flow paths (poro/perm distribution). The flow paths are controlled by the facies distribution within a geological model. If the facies distribution in the model does not describe the flow paths in the field sufficiently the model will fail to history match without the addition of significant reservoir engineering patches and fail to forecast effectively. By assessing the performance of the initial geological model against dynamic data, for example initial pressures, it is possible to identify static models that show fluid pathways that fit to the dynamic data, rejecting those that fail. This allows the identification of a number of satisfactory geological models.
