Abstract

Vertical seismic profiling also known as borehole seismic has numerous applications in the game of hydrocarbon exploration. Its utility has expanded from simple time- depth information to reservoir characterization. It acts as a vital link between geology and seismic. Typically, three- component receiver is used in VSP data acquisition for recording both compressional energy (P) and mode converted shear waves(S). Converted waves(C-wave) are generated only when source is located a few hundred metres from well. Converted wave data after processing with special algorithm is used for correlation with three component surface seismic and give additional information about geology like fluid content, fracture geometry and orientation. In this paper, the methodology adopted for processing of converted waves has been described with real data examples
