Testing Cumulative Semivariogram Modelling Technique on Bouguer Anomaly

Abstract In principle spatial correlation is depicted using Semivariogram technique. Cumulative Semivariogramtechnique is the alternative for conventional Semivariogram technique has various advantages but not widely used in gravity modelling. Our objective is to test the Cumulative Semivariogram technique in gravity modelling by estimating Bouguer Anomaly in Krishna Godavari KG basin area by fitting the experimental Cumulative Semivariogram against the theoretical Cumulative Semivariogram and fitting the experimental Semivariogram against theoretical Semivariogram. Hence calculate the value obtained at the random point using appropriate kriging technique after Cumulative Semivariogram model fitting and Semivariogram model fitting. Finally calculate the percentage variation between the predicted values obtained from both the techniques with the observed Bouguer Anomaly. Percentage variation will give an insight whether Cumulative Semivariogram technique is the better alternative than Semivariogram technique for geostatistical modelling or not.
