Coupling Electrical, Seismic and Pressure Sensor Arrays for Effective Reservoir Monitoring

H-04 COUPLING ELECTRICAL SEISMIC AND PRESSURE SENSOR ARRAYS FOR EFFECTIVE RESERVOIR MONITORING Summary 1 Arrays of permanent sensors to be deployed along wells are currently being developed for reservoir monitoring. Three main physical principles can be envisaged for monitoring saturation changes: resistivity pressure response to well tests and seismics. They are providing independent pieces of information that complement one another. Introduction One important challenge for reservoir management in the coming decade is to monitor fluid movements in hydrocarbon reservoirs with in view to optimize their drainage [2]. Resistivity acoustic and pressure monitoring techniques can be considered. They differ in the
