ABSTRACT
resolution
aeromagnetic data acquired along closely spaced flight lines
provide information that can be used to detect magnetic enrichment produced by
vertical
microseepage from hydrocarbon traps. Aeromagnetic data acquired prior to drilling display
characteristic micromagnetic hydrocarbon signals over areas in which significant
production is later established. Three examples of newly discovered west Texas
Pennsylvanian production, one example of Jurassic production in Alabama, and examples of
various fields in Texas Railroad Commission District 4 are presented. Seismic and
aeromagnetic data from an unsuccessfully drilled micromagnetic lead are reviewed, and
aeromagnetic data over large nonprospective areas are displayed. To date, 87% of the
micromagnetic leads that subsequently have been drilled have yielded economically
successful fields or field extensions.
