Technical Paper: Marine Controlled Source Electromagnetics (mCSEM) 3D Test over a Known Target

Society: EAGE
Paper Number: G007
Presentation Date: 2008

This presentation details a test of newly acquired 3D mCSEM (marine Controlled Source ElectroMagnetic) data over a known field with the aim of demonstrating the technology and achieving an in-house validation of the technique to improve understanding on how best to use these data and integrate them into our interpretation methodology. A target offshore West Africa was chosen as it represented a known accumulation with complex, 3D geometry, stacked pay in a realistic exploration setting and depth. There was also consideration for establishment of a baseline for possible future 4D EM monitoring – a subject of ongoing R&D.
