Airborne Gravity & Magnetics ? A fast track multi-system approach for petroleum exploration

Abstract

Recent advances in mapping technologies coupled with the emerging needs of the exploration industry to precisely characterize the sub-surface systems, have led to the resurgence in interest for gravity and magnetic (so called potential field) methods in oil and natural gas exploration. The need for acquiring large potential field data sets at greater speed over highly prospective and frontier areas is increasing the demand for airborne measurement systems. In response to this need, UTSAeroquest offers the latest version of airborne gravity systems called TAGS (Turnkey Airborne Gravity System) on a fixed wing geophysical survey aircraft, which is already equipped with a magnetic acquisition system as well as radar and laser altimeters. Prior to offering the services of this new system, a pre-purchase test of the gravity meter was undertaken. The results provided a high level of confidence in offering this multisystem airborne geophysical approach to the petroleum industry.
