Large-Scale Multiphysics Airborne Geophysical Survey in Saudi Arabia: Results of the Glass Earth (Pilot) Project

Recent developments in large-scale geophysical inversions made it possible to invert the results of entire airborne geophysical surveys over the large areas into 3D models of the subsurface. This paper presents the results of interpretation of the data acquired by a multiphysics airborne geophysical survey in Saudi Arabia. The project involved the acquisition, processing, and interpretation of airborne electromagnetic, gravity, and magnetic geophysical data over an 8,000 square kilometer area. All the collected data were carefully analyzed and inverted in 3D models of the corresponding physical properties of the subsurface, including 3D density, magnetization vector, and conductivity models. This paper summarizes the interpretation of all geophysical data sets collected during the field airborne survey.
