EXPERIMENTAL WORK IN SEISMIC DATA ACQUISITION
EXPERIMENTAL WORK GUIDELINES FOR SELECTION OF EXPERIMENTAL SITE Experimental site should be free from sub surface faulting Continuity of reflection events must be there Experimental site should represent the whole area It should be free from surface undulations, industrial & cultural noise, power line etc. Full suite of experiments is to be carried out at every experimental site All efforts should be made to control the vehicular & other cultural noise if any The experimental spreads should be oriented along the proposed profiles. The following experimental work is to be carried prior to regular seismic work at least at one site (preferably in the centre of the area) within the survey area to fine-tune the acquisition parameters. 1. Up-hole survey 2. Shot hole depth and charge size optimization 3. Noise survey 4. Array test UP-HOLE SURVEYS : Objective: 1. To optimize the charge depth for noise survey.
