Abstract:The vertical seismic profiling (VSP) on WIO-3 anticline in North Bay water was done, on a drilling platform, by using water gun source and digital seismic logger. The sampling rate is 1 ms, the geophone intervals are 20-50 meters, and the offset 50-60 meters, in addition to the conventional method for Land data, some special procedures, such as separating upgoing wave, downgoing wave and side waves, etc. are also used in data processing, corresponding sections being provided for each processing procedure.VSP has higher S/N ratio, higher verticai resolution. It enhances weak reflections from deep layers and provides more accurate velocity information.
