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.

Surface Exploration Case Histories: Applications of Geochemistry, Magnetics, and Remote Sensing provides an overview of successful applications of surface exploration methods. Through a series of independent case histories, this volume presents clearly documented evidence that demonstrates how surface exploration methods can significantly reduce exploration risk and finding costs: geochemical, magnetic, and remote sensing. The 19 chapters in this volume reflect the broad scope of applications for these methods: frontier basin reconnaissance, prospect development, prospect evaluation, and field development and production. The case histories span the globe: 1. North America 2. Africa 3. South America 4. Europe 5. Middle East 6. Australia. This book will interest explorationists and managers who seek to get the most out of each exploration dollar.
