A case study of how medium resolution ASTER satellite data can be used to screen basins for the evidence for onshore surface seepage – poster presentation from AAPG Hedberg Research conference “Hydrocarbon Microseepage: Recent Advances, New Applications, and Remaining Challenges”, Houston, June 2019.
Reducing exploration risk by confirming petroleum source and charge is a major component of petroleum system analysis and is a critical phase of any exploration program.
The use of cloud-penetrating radar data in offshore basins to detect and isolate slicks emanating from sea floor seepage of oil and wet gas is now seen as an important pre-requisite to screening basins prior to far more extensive exploration. The same task onshore relies on optical satellite data that has the disadvantage that resultant images can be obscured by cloud, extreme vegetation cover and highly heterogenous geology, both physically and chemically.
However, many case studies have demonstrated success in targeting onshore seeps, whether looking at spectral microseepage anomalies, direct macroseepage of oil and bitumen at the surface or even vegetation anomalies.
