Integrated Approach Using Subsurface Geology, Aeromagnetics, Surface Geochemistry and 3-D Seismic in Discovering New Conventional Reservoirs

Abstract

An integrated approach is used by many companies in the industry that is restricted to subsurface geology and 3D seismic. By adding aeromagnetics and surface geochemistry allows a more definitive approach. In many producing areas aeromagnetics can be used to determine faulting that can be related to potential structural and stratigraphic traps and to delineate potential migration pathways. In some basins such as the Forest City, isolated structures are the norm but not all structures are productive. Aeromagnetics can help determine likely areas of oil migration. Surface geochemistry provides a tool to determine if micro-seepage is present at the surface. Historically an area of no anomalous surface geochemical readings typically implies a reservoir with no petroleum of significance present. By using a group of complimentary exploration tools this helps reduce but not always eliminate risk in drilling. The Arikaree Creek and Bolero fields in the Denver Basin and several Bartlesville sand producing fields in the Cherokee Basin using this integrated approach will be discussed.
