Gravity regional residual separation - the ARGeo

Gravity –regional residual separation Kristján Ágústsson, Iceland GeoSurvey Slides from Gylfi Páll Hersir. Merki ÍSOR á ensku. Regional field – regional and residual anomalies. Bouguer anomaly fields are often characterized by a broad, gently varying, regional anomaly on which superimposed higher wave number local anomaly occurs. Usually in gravity surveying it is

The current study is focused to determine residual and regional gravity anomalies for understanding basin architecture of the Cauvery Basin. In this study, the basement of the Cauvery Basin was determined using two-way-travel time seismic data and well log data obtained from eight exploration wells. Depth data from selected 2D sections were used as input data for a

Regional-residual separation of potential field: An ...

Adequate separation of regional-residual components from observed gravity anomaly is always a challenging task in gravity interpretation. Several techniques have been developed for effective regional-residual separation, however, no single approach can perfectly accomplish the job. In this work, a hybrid approach has been proposed with an objective to enhance the

01.02.2017  Regional - residual separation is a crucial step to obtain the residual field. The expressions “residual” and “regional” are used to make a clear distinction between anomalies related to shallow and deep sources. In many cases, the choice of regional depends on the residual anomalies to be interpreted (Beltrao et al., 1991).

SEPARATION OF REGIONAL AND RESIDUAL ANOMALIES BY

The correlation coefficients between residuals of two consecutive orders also give the same result. In the relaxation technique, a linear trend is assumed within each cell of the mesh of a square grid. A set of such linear segments can approximate any complicated regional trend. The performances of these two techniques have been evaluated using simulated gravity
