Abstract
Fractal dimension analysis was carried out for optimum designing of 2D gravity survey network and to find out an optimum range of gridding interval to generate least aliased Bouguer anomaly maps. As a test case, this method has been successfully applied to the Jabera-Damoh region of Vindhyan basin, which is considered as a potential hydrocarbon bearing area (Das et al., 1999). We aimed to delineate accurately the lateral extent of the possible hydrocarbon bearing structure. A range of optimum gridding interval for gravity data set was suggested using box counting method of fractal dimension determination. Bouguer anomaly maps of the region are prepared using the optimum gridding interval. For the first time, these anomaly maps clearly outline the gravity evidences of an anomalous rifted structure, which is bounded by parallel faults on its either side.
