Assessment of Reservoir Properties using Applied Rock Physics SeismicInversion for Near-Field Exploration in a Niger Delta Field

摘要

A quantitative seismic interpretation (QSI) approach in assessing reservoir properties of a near-fieldexploration discovery is presented. This approach demonstrates the integration of rock physics model and seismic inversion to determinethe lateral extent of the reservoir complex, improve the understanding of geometry and connectivity of thereservoir sands encountered in this field; and improve confidence in estimates of the resource base. An integrated interpretation approach that incorporates seismic and well log data sets, together withavailable relevant reports is adopted to reduce interpretation risk inherent with the study location. Thehydrocarbon bearing reservoir sands were characterized, based on their elastic rock properties responses,to predict reservoir parameters for reservoir architectural delineation from seismic data volume. The resultsprovide insight to address subsurface uncertainties associated with reservoir connectivity, and future infillwell count determination for production optimization and possible reserves addition.
