Quantitative seismic interpretation based geo-cellular and dynamic model integration in a waterflood environment

摘要

This study presents quantitative seismic interpretation based innovative methods of integrating the seismically driven geo-cellular model into the dynamic model and closing the loop for improved understanding of the reservoir. The example presented here is from an offshore field, Sarawak Malaysia. The goal of this study was to establish a detailed integrated recipe for a highly flexible and powerful method of building fit for purpose static and dynamic models that will be acceptable in full field development programs. An innovative method was tested and applied for geo-cellular modeling where reservoir architecture and reservoir probabilities from geostatistical inversion, lithological information from petrophysical interpretation, and facies from geology were integrated. To this end, the dynamic properties were integrated into the geo-cellular model to study inter-block communication. The proposed integrated method offers optimized subsurface models which are being utilized in waterflood monitoring, reservoir connectivity analysis between the wells, and optimizing the infill and water injector drilling programs.
