Abstract

Residual statics usually are discussed in terms of applications to land data. It has produced dramatic improvement in fold belt area where terrains have rapid variations in elevation. However residual statics have provided satisfactory results in irregular sea-floor in shallow waters and areas with rapidly varying velocity in the sediments near the water bottom. In complex near surface setup where single pass of residual statics falls short of expectations the processor is tempted to apply multiple passes of the same to ameliorate the stack response. Application of repetitive passes of residual statics rakes up a few queries like amenability of the seismic data towards residual statics, adequacy of number of passes and the benchmark to be achieved as far as residual statics
