AB - Reservoir compartmentalization (vertical and lateral) is often a major uncertainty at the field appraisal stage, impacting important investment decisions. Unfortunately the most definitive compartmentalization data (dynamic production data) are not usually available so early in field life. This paper illustrates how early indications of compartmentalization can be achieved by integration of various types of static data, using an example from the Ross oilfield, UKCS. Here, integration of oil molecular maturity parameters, GC fingerprinting, PVT data, well test analysis and fault seal analysis with interpretation of 3-D seismic revealed the presence of several sealing faults, and thus enabled the field to be described in terms of its natural segmentation. Vertical compartmentalization was investigated using a combination of oil geochemistry (maturity, GC fingerprinting), residual salt analysis and high-resolution stratigraphy, revealing a continuous shale that has a lateral extent of >5 km; it divides the reservoir into two main layers. The results of this study helped to decrease uncertainty in field development planning. The key message is that there are many tools available in the toolkit to aid in assessing compartmentalization, but individually they each only give part of the picture. It is therefore important to use several tools in combination.
