Complexity in the shallow section is a challenge, where control is mitigated by the inability to image shallow geology in a timely and cost effective way. Shallow velocity models traditionally use whatever technology is best able to image where seismic can’t, and shallow hazards such as voids and Karsts frequently cause circulation losses that cannot be mitigated unless expensive ground acquisition techniques are used.
In this webinar we discuss the application of Airborne Full Tensor Gradiometry (Air-FTGÂ®) in several settings in the Permian basin where FTG data has been integrated with existing client seismic data and has resulted in sufficient detail to provide a new velocity model as a starting point for an improved PSDM.
Examples will also be provided where FTG produced a standalone risk map for shallow drill hazards over the entire lease, entirely from data that took days to acquire. Under a month to process and interpret, available to clients on a per-square-mile, multiclient basis to make it cost effective. Any limitations will also be addressed, as no methodology is without its limits, and the key here is to understand where FTG can help, and how it integrates with what the client already knows, and can steer where they go next.
The application of the technology applies to any area Worldwide where complexity in the shallow section exists over an area of interest. It is another tool that geoscientists can use to improve depth migration of their seismic data and de-risk a lease before well planning. Statics corrections can be applied using FTG data, and operators can gain access to a real source of shallow control without long and expensive land acquisition. In each example we discuss where it is better to have a high definition image of the shallow that is fast and cost effective to acquire, with no permitting issues or boots on the ground. Full Tensor Gradiometry data is an under-utilized solution to a multitude of challenges, but this webinar is intended as an accessible introduction to Air-FTG as a solution that focuses on a clients needs in the prolific and challenging basin in America.

Processing Geoscientist at Bell Geospace
Katherine Chase has varied experience in the processing of potential field data, and is currently involved with FTG Research and Development.
Lead Geophysicist at Bell Geospace
Alan is a subject matter expert in potential fields and has been involved in the integrated interpretation of potential field data since 2004. Prior to his potential fields experience, he attended the University of Louisiana at Monroe where he obtained degrees in Geology (B.S, 2002) and Geoscience - hydrogeology specialty (M.S., 2004).
His global experience varies from mega-regional to prospect scale projects, primarily in areas where seismic imaging falls short in efforts to assess geometry risk. His specialties include 2D and 3D inversion, magnetic depth methods and plate kinematic modelling. He also is a contributor to a patent in the evaluation of plate kinematic models using potential fields methods.
He has also served on the SEG gravity and magnetics committee and is the current coordinator for The Meter Reader for the SEG publication, The Leading Edge.
