Today, 75 years after gravity and magnetics first entered the exploration scene, potential fields input continues to be embraced worldwide, especially where seismic sections are problematic. Gravity and magnetic applications in seismic processing have gained significant respectability. And who would have thought that a new technology option would emerge using magnetics in downhole MWD applications to provide cost-saving measurements at the drill site?
Discussed is the gravity and magnetic applications that have evolved in tandem with the complexity of modern exploration technology. Full tensor gravity gradiometry data and visualization techniques have added to data resolution and applications. An example is shown to emphasis that the validity of input data must be made. It is important that data processing and/or data merging techniques applied to potential fields data retain the full fidelity of the measured data.
