Abstract

The problem of imaging the sub-surface accurately is always a challenge to the Geoscientists. This requires a proper understanding of the geology of the area/basin, objective of survey, adequate acquisition geometry to delineate the prospect and overall a smart processing of the data. In this paper a 3D land data pertaining to Cauvery Basin has been taken into consideration for 3D PSTM. Kirchoff Pre Stack Time Migration (PSTM) is a more advanced and technically accurate processing algorithm, and due to reduction in computing time, it is being used in a large scale in the Oil industry as a basic processing tool. The by product of PSTM processing, CRP gathers through Kirchoff algorithm can regularize the acquisition geometry, through geometrical weighting.
