Accuracy of Sharp Inversion of CSEM Data Constrained by Seismic

It is well known that sharp inversion of CSEM data constrained by seismic can produce very accurate resistivity estimation. However frequently asked questions are: is the inversion result still valid if the depth and the thickness of the layers estimated from seismic interpretation are affected by some inaccuracy? How this inaccurate depth/thickness estimation propagates through the inversion of the CSEM data? In this paper we try to answer these key questions through synthetic tests and with application to real data where a well control exists.
