RESERVOIR MONITORING IN A LAMINATED RESERVOIR USING 4-D TIME LAPSE DATA AND MULTICOMPONENT INDUCTION DATA

摘要

Time lapse seismic measurements of a laminated reservoir (401) including sands and shale are processed to determine changes in the laminated reservoir (403). An initial petrophysical model is obtained at a well bore from measurements made with a multi-component resistivity-logging tool (405). Changes in the amplitude versus offset behavior of the reflections from the top of the reservoir are indicative of changes in fluid saturation and/or formation pressure.
