Title: Landsat Imagery as Tool for Determining Potential Oil and Gas Resources: ABSTRACT

Author(s): Ken M. Morgan, Jack Walper, Don Morris-Jones

Article Type: Meeting abstract


Several hydrocarbon-bearing areas in the world have been examined using custom processed Landsat imagery along with geologic interpretations to determine potential hydrocarbon resources. Project areas are located along the Texas Gulf Coast, the western Overthrust Belt, the Athabasca Canadian region, and the South China Sea area.

Digital Landsat data were processed to produce 1:250,000 scale edge-enhanced, false-color, and high pass filter images. All the images were geometrically corrected with topographic controls and nonlinear deconvolution techniques (coverage = 13,000 sq mi or 33,800 sq km). These specially processed images have been used to map surface geology, lineament systems, and geomorphic anomalies in relation to subsurface geologic and geophysical data. Project areas are defined in terms of their tectonic genesis, structural trends, and hydrocarbon potential. Numerous exploration targets and several modes of hydrocarbon entrapment are identified by image interpretation.

The pressing need for more energy resource demands an accelerated large-scale exploration program. Landsat imagery has been utilized as a tool in the four project areas for structural, stratigraphic, and geomorphic analysis to locate geologic anomalies. Image analysis provides a better understanding of the regional stress-strain relations for tectonic correlation. This information can be used to identify a suite of exploration targets to be integrated into industry seismic programs.
