Abstract

This paper illustrates the use of an integrated analysis of HRAM data and RADARSAT-1 images for detection and analysis of geologic structures in mature and frontier basins. The HRAM images provide detailed information on basement structures, weakly magnetic faults, and fracture systems in the sedimentary section, and other features that contain magnetic material anomalous to the surrounding rock units. The RADARSAT-1 images are used to constrain the analysis of the HRAM data, as well as to expand the interpretation into areas that are not covered by the HRAM surveys. A series of examples supported by surface and subsurface controls has been used here to illustrate our integrated approach to the analysis of these two reconnaissance exploration tools.

In the shallow waters of the Gulf of Mexico, HRAM images are used to map the inventory of complex salt bodies and to establish their structural linkage with extensional, listric, normal fault systems. In the foothills region of northeastern British Columbia, the integration of HRAM images and RADARSAT data leads to the recognition of (1) exposed and buried folds and thrust faults, which form the key hydrocarbon traps of this region, and (2) major cross-trending fault zones that form a fractured-reservoir fairway.

Finally, in a frontier exploration area (the onshore basins of Gabon), we have used newly available HRAM data, RADARSAT-1 images, and regional seismic data to investigate the hydrocarbon potential of deep-seated basement structures in the Dianongo Trough. The regional coverage of the HRAM data and RADARSAT images allows us to establish the structural style of different parts of the basin, identify new exploration concepts and leads and, most important, map key basement structures that lie below the salt layers of this basin. Previous attempts to explore for such subsalt plays were hindered by the poor quality of the seismic data for these exploration targets.
