Abstract

Summary

The integrated gravity modeling is a concept dedicated to delineate accurately the structural lineation and framework using the rock density heterogeneity principle. It’s based on qualitative and quantitative interpretations of gravity data.

Since the fault zone and diapirs are the main cause of the seismic quality degradation, especially in 2D seismic, using a specific gravity analysis workflow will enable the mapping of fault network (even sub-seismic scale faults) and tightening the structural model interpreted from the seismic.

Ultimately, integrating gravity interpretation (qualitative and quantitative), seismic and well data and surface geological data as input for gravity modelling, will help to constrain the basin architecture, and to map the deep structures (further than seismic investigation depth).

This tool have been used to identify subsurface anomalies which could be anything from horst-blocks to basaltic intrusions or diapirs, but also to mitigate the petroleum exploration risk related to trap definition and integrity in an under-explored area with limited data set.
