ABSTRACT

In Western Canada, and probably elsewhere around the world, "magnetically enhanced zones" above microseeping hydrocarbon reservoirs can exhibit distinctive Previous HitmagneticNext Hit signatures that are characteristic of the reservoir. These distinctive Previous HitmagneticNext Hit signatures have proven to be invaluable for hydrocarbon exploration, and we have achieved 85% exploration success using ground-based Previous HitmagneticNext Hit and radiometric techniques in Western Canada. Differences in timing and duration of microseepage and differences in composition and pressure of the microseeping hydrocarbon gases from separate petroleum systems probably control the Previous HitmagneticNext Hit mineralogy, Previous HitmagneticNext Hit grain-size distributions, Previous HitmagneticNext Hit susceptibility, and natural remanent magnetization (NRM) directions in the magnetically enhanced zones. Together, these differences can yield diagnostic "residual" (remanent + induced) short-spatial-wavelength Previous HitmagneticTop anomalies above different reservoirs.
