Abstract
P158 POLYCOR Method of Statics Correction and Raw Data Quality Control for 3D Acquisition Geometries A.A. Tabakov* (Central Geophysical Expedition) A.V. Kopchikov (Geovers Ltd) V.N. Ferentsi (Geovers Ltd) V.L. Eliseev (Central Geophysical Expedition) & A.A. Zaznobin (Geovers Ltd) SUMMARY «POLYCOR» is an alternative method of static shifts correction in CDP data processing based on multiple correlations. It is based on four-factor model of time shifts. This model includes kinematical shifts dip shifts and shot point (SP) / observation point (OP) statics. «POLYCOR» method features high noise immunity. Accuracy of SP and OP statics determination in practice does not depend on
