Technical Abstract

Migration Confidence Analysis: Resolved Space Uncertainties

Back to Technical Content
We show how the method recently proposed in Messud et al. (2017; 2017b) allows to consider “resolved space” tomographic uncertainties in complement to total tomographic uncertainties. Resolved space uncertainties are obtained by restricting the tomography model space to the one that can be resolved by tomography. Total uncertainties mostly quantify the illumination uncertainties, whereas resolved space uncertainties tend to be more correlated to the final tomography model. We illustrate how those two uncertainties give complementary information for the subsequent seismic interpretation.
