ABSTRACT:
Surface seismic sources are used to simulate crosswell data between the two wells, and, using surface receivers, reflection seismic data are obtained over the region between the two wells. Reflection data are preferably obtained from reflectors both above and below the reservoir. Tomographic analysis of the simulated crosswell and reflection data gives a model of the reservoir. Changes in the model are indicative of reservoir fluid changes, pressure changes, or compaction.
