Abstract
IS-2 PROBLEMS IN MEASURING THE COHERENT NOISE PRODUCED IN NEAR-SURFACE SCATTERING C. REGONE SUMMARY “Measurement and identification of 3D coherent noise generated from irregular surface carbonates” EAGE 63rd Conference & Technical Exhibition — Amsterdam The Netherlands 11 - 15 June 2001 1 When near-surface scattering produces high levels of coherent noise successful acquisition design requires knowledge of the noise characteristics. Most field tests conducted to measure noise characteristics have serious deficiencies. 2D methods such as walkaway wave tests and CMP stacked sections may sometimes reveal the presence of in-line scattered noise. Often scattered energy arrives from many azimuths with equal
