Abstract

Low-level, high-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.
