oa Faults Enhancement Based on 3D Geological Model Analysis

A methodology for faults enhancement from seismic volume is presented. This method proposes to detect the faults distribution on the basis on the 3D analysis of a continuous geological model. This geological model is obtained by using an innovative technique based on global optimization algorithms in the PaleoScan software. The analysis of the geo-model allows to detect the faults network with a high level of accuracy and to estimate the throw along each fault plane. This approach has been successfully tested on various data sets where the throw analysis was required to identify the sealing faults for geo-steering and well placement applications. A case study in Nigeria is presented.
