Abstract: Integrated Analysis of High Previous HitResolutionNext Hit Aeromagnetic And Satellite Imagery Data for Hydrocarbon Exploration in Frontier and Mature Basins

Zeev Berger, Colin Nash, Christian Ellis, Bill Witham

Recent improvement in the collection and processing of high Previous HitresolutionNext Hit aeromagnetic data provides, for the first time, information on the spatial distribution of geological structures in the sedimentary section. The magnetic data, which is presented with a series of color images, can be easily merged and correlated with satellite imagery data, air and space borne radar and conventional aerial photography. The integration of these two different reconnaissance tools provides excellent means for structural mapping and early evaluation of hydrocarbon plays in both frontier and mature areas.

A series of examples supported by both surface and subsurface controls are used to illustrate the exploration application of these two different data sets. In the frontier fold and thrust belts regions of the North Slope Alaska, the Andes of South America, and the Canadian Foothills, high Previous HitresolutionNext Hit magnetic images and side-looking air and space borne radar data are effectively used to improve the interpretation of geological structures above the detachment levels. This data was also used to identify the presence of basement involved reactivated structures and related migration pathways. In less deformed and more mature areas, such as the Central Basin Platform of West Texas and the Peace River Arch of the Western Canada Basin, the integration of high Previous HitresolutionNext Hit magnetic images and La dsat TM data leads to the recognition of new faults and fracture systems and related hydrocarbon plays.

The availability of high Previous HitresolutionTop magnetic surveys and new space borne radar systems such as ERS-1, JERS-1 and RADARSAT should play a significant role in exploration of the heavily vegetated fold belt regions of the tropics as well as the vast plains and plateaus of the South American continent.
