Abstract

Building a reservoir model from seismic data interpretation can be very time consuming and cause incorrect or poor quality results without any specific methodology. Limitation of the seismic scale regarding to the reservoir detail needs, incomplete horizon or fault picking and structural 3D incoherencies can prevent from getting structural surfaces adapted to structural reservoir modeling. In addition, geomodel software limitations must also be taken into account in order to ensure that critical structural heterogeneities described from seismic interpretation will be ranked and adapted for an appropriate modeling . The following paper proposes a methodological workflow that enables the delivery, of representative and appropriate structural surfaces, ready for reservoir modeling. The workflow underlined how artifacts, incoherencies and software limitations can be corrected. All specialists, geophysicist, geologist and reservoir engineer must work together early in the process in order to define structural modeling strategy and choices in agreement with structural, sedimentology and dynamic criteria. In any case such workflow will ensure a better description of essential heterogeneities. In addition, as the reservoir grid remains consistent with seismic data then lithoseismic cubes can be considered to constrain the facies and petrophysical modeling.
