Description 491-496
Three different satellite gravity data e.g.
Hwang gravity (High Resolution), GRACE gravity and ERS-1 gravity over the
Bombay High region in the western Indian offshore were examined in the present
study. Hwang gravity data has been found most suitable for exploration in the
offshore region and for lithospheric studies, apart from utilization of
non-altimetric source of satellite gravity e.g. GRACE data and ERS-1 altimeter-derived
gravity. Further 2D/3D image generations and enhancement from high resolution
gravity data have been found useful for delineation of Bombay High structures
which is highly prospective for oil exploration. In addition, the major trends
found in the western offshore are NE-SE, NNW-SSE and E-W as observed using 3 ×
3 left diagonal edge detection technique over the gravity anomaly image.
