Abstract
Summary
A full-scale 3D surface-to-borehole CSEM survey was carried out to map the position of the current waterfront around a test well in a producing oil field. Pre-survey modeling studies and experimental results show agreement in terms of measured signal levels, repeatability errors and expected sensitivity to targets. The vertical electric field shows the largest sensitivity to the spatial resistivity distributions in the reservoir. The obtained results provide the baseline for future time-lapse surveys targeting the monitoring of the water-oil saturation changes.
