Evaluation of Reservoir Connectivity Using 4D Seismic and Production Data

A well2seis technique is proposed to automatically correlate 4D seismic signal to well production activities. It provides a framework for estimating the drainage radius of wells, and understanding the spatial reservoir connectivity for reservoir model maturation. This technique is incorporated into a consistent workflow that assists 4D interpretation for the purpose of model maturation, well planning and reservoir management. We applied this workflow to a compartmentalized North Sea field where the inter-reservoir communication pattern needs to be determined. The study on the field demonstrates that the well2seis workflow can assist in maximizing the value of 4D seismic and production/injection data in the decision making process.
