Abstract: Geophysical
Evidence of
Anomalous Near-Surface Rock Properties Associated With Hydrocarbon Seepage,
The Significance and Potential
There is growing evidence that the upward
migration of light hydrocarbons escaping from a reservoir and the accompanying
geochemical processes cause changes in the physical properties of the overlying
near-surface rocks, changes that are geophysically detectable. Surveys
carried out in several areas, compiling data of different types, geological,
surface geochemical, surface geophysical
and high resolution airborne magnetics,
are presented to illustrate the resulting multidiscipline correlation of
information and allow reflection on its suggested significance and petroleum
exploration potential.
