What is it about?
This paper will focus on the 3D Euler technique described by Nabighian and Hansen (2001) in the context of use with more recently available high resolution data such as High Resolution Aeromagnetic (HRAM) and Airborne Gravity Gradient (AGG) acquisition. These data allow much more detailed estimation of source depth and definition than previously seen by the author.

Why is it important?
This paper displays two examples of using 3D Euler depth estimation to illuminate sub-salt volcanic structure (Figure1) and thrusted carbonate platforms (Figure 2). The additional information presented by depth estimation from potential field data is seen as valuable as the seismic imaging in both contexts is difficult to interpret due to complex overlying salt structure or limited in extent due to acquisition costs.
Perspectives
If used carefully, 3DEuler depth estimation can provide important, additional insight to sub-surface structure without the need for information or assumptions on the density or susceptibility contrasts. The main requirements being that there are sufficiently high-resolution data and that there exists a strong contrast in density or susceptibility at (or related to) the structure of interest.
