Seismic Driven Reservoir Characterization: Case Studies of Reservoir Architecture Definition and Reservoir Rock Properties Distribution

Abstract

Seismic technology advances and well established reservoir workflow industry practices have led to a more accurate description of subsurface through reservoir models. Seismic driven reservoir characterization is a dynamic process in which iterative calibration and interpretation of information contributes to geologically sound and quantitatively calibrated model. Whether the main goal of the reservoir characterization is structural or stratigraphic, or even a quantitative reservoir property calculation and distribution, it is essential to focus efforts that contribute to: (1) the quality of the input data; (2) the best acquisition/processing methods and, (3) the calibration and correction of seismic-well log data that contribute in lowering uncertainties.This presentation deals with the cons and pros in using seismic as main driver while building reservoir models. Three cases are presented Case 1: Seismic reservoir architecture of prograding events in a falling seal level stage.
