Seismic traces analysis method using a statistical calibration technique to deduce geological properties.

摘要

P - The method applies to an underground formation for which geological data obtained by coring or logging in wells (W1 - Wk) passing through it and seismic data obtained by an exploration campaign are available seismic reflection type 3D for example. It is based on a statistical calibration technique with a statistical calibration obtained by comparing the local geological data (measured in wells) with seismic attributes read on seismic traces (RW1 - RWk) obtained in the immediate vicinity of each well. This calibration provides an empirical relationship that can be applied to all seismic traces of the field to infer the associated geological features, benefiting from the much denser spatial coverage allowed by seismic prospecting.
