ABSTRACT: Remote Sensing for Energy and Mineral Exploration in Circum-Pacific Region

F. F. Sabins

This report summarizes some of the Chevron Corporation's applications of remote sensing to energy and mineral exploration in the Circum-Pacific Region. Mineral exploration in Chile and Australia uses digitally processed Landsat thematic mapper (TM) images to (1) map regional and local structure and fracture patterns, and (2) recognize hydrothermally altered outcrops with concentrations of iron oxide, secondary clays, and other alteration minerals.

Landsat and SPOT satellite images are also employed in oil exploration to map structure and stratigraphy. In regions with prevailing cloud cover, however, such as Indonesia and Papua New Guinea, radar images acquired from satellites and aircraft are valuable for two major reasons: (1) Clouds are penetrated, and (2) the low-angle illumination enhances subtle topographic features that may be the surface expression of geologic features.

These concepts are illustrated with images and interpretations from various Circum-Pacific regions.
