Weighted Euler deconvolution of gravity data

Geophysics, 1996
Abstract Euler deconvolution is used for rapid interpretation of magnetic and gravity data. It is particularly good at delineating contacts and rapid depth estimation. The quality of the depth estimation depends mostly on the choice of the proper structural index and adequate sampling of the data. The structural index is a function of

Euler Deconvolution of GOCE Gravity Gradiometry Data

2012
Euler deconvolution is a standard tool of geophysical prospection. In the early 1980s, the beginning of its development, it was used for the evaluation of magnetic field data. However, since the 1990s, together with the increasing power of computers, research was intensified on the aspect that Euler deconvolution is also applicable to gravity ...

Euler Deconvolution Applied to Potential Field Gradients

Exploration Geophysics, 2004
Euler deconvolution is a useful tool for providing initial estimates of the locations and depths of magnetic and gravity sources. When it has been used with aeromagnetic data, it has traditionally been applied to the total magnetic field intensity. In recent work it has been also applied to the vertical gradient of the field with much success.

Euler deconvolution: Stability and parameter bias analysis

SEG Technical Program Expanded Abstracts 1997, 1997
We present theoretical uniqueness, stability, and parameter bias analyses for the simultaneous estimation of: the structural index the horizontal and vertical positions and respectively) of a point magnetic source, and a baselevel b, using Euler’s differential equation. We found that and are independent of the other parameters and can be estimated from

Egregious Euler Errors - The Use and Abuse of Euler Deconvolution Applied to Potential Fields

Proceedings, 2012
Euler deconvolution is commonly applied to magnetic and gravity interpretation problems. For the deconvolution to be successful, care must be taken to choose parameters properly. 1. The interpretation problem must be appropriate to the method (only one depth to be estimated at each point). 2.

Automatic Detection of Uxo Anomalies Using Extended Euler Deconvolution

18th EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2005
The paper presents an algorithm for automatic detection of UXO anomalies in total-field magnetic data based on the concept of structural index (SI) of a magnetic anomaly. The magnetic field produced by a dipole-like, source such as a UXO, varies with inverse distance cubed and therefore has an SI of 3.

Euler deconvolution in the presence of sheets with finite widths

Geophysics, 2010
Abstract Euler deconvolution of magnetic fields, induced by sheets with nonnegligible widths, provides source-location estimates that are biased away from the true locations. I have derived formulas for these biases and used the equations to model diffuse solution patterns that are owing to the interplay between integer structural ...

Euler deconvolution of vertical profiles of potential field data

SEG Technical Program Expanded Abstracts 2006, 2006
Euler deconvolution has become a standard tool in rapid, semi-automated interpretation of potential fields. Its success derives from its flexibility, providing the source position and a parameter describing the shape of the source (structural index, SI) for all the possible one point sources (point, horizontal or vertical line, dike, contact).

Interpretation of Isolated Gravity Anomalies Using Euler Deconvolution

64th EAGE Conference & Exhibition, 2002
P114 INTERPRETATION OF ISOLATED GRAVITY ANOMALIES USING EULER DECONVOLUTION 1 Abstract We have developed a simple approach to determine simultaneously the horizontal location depth and structural index of simple geometrical structures from isolated gravity anomalies based on Euler’s homogeneity equation.
