3D Reservoir Model and Resource Estimation for a North Sea Oil Field from Quantitative Seismic and CSEM Interpretation

Understanding reservoir properties and fluid distribution is the aim of petroleum geophysics, in particular in the field appraisal and development phases. The ultimate goal is not only to identify and delineate hydrocarbon charged reservoirs, but to quantitatively determine the volume and distribution of oil and gas contained. Since no single measurement has the required response properties to achieve this, it is now recognized that integration of different types of data with complimentary sensitivity will be essential. In this study, we describe a quantitative, joint interpretation of 3D seismic and 3D controlled source electromagnetic (CSEM) data from the Troll western oil province (TWOP), an oil and gas field in the Norwegian North Sea.
