Interferometric Imaging Condition

C019 Interferometric Imaging Condition P.C. Sava* (Colorado School of Mines) & O.V. Poliannnikov (University of Colorado) SUMMARY Accuracy of depth seismic imaging velocity models used for wavefield reconstruction. Models can be decomposed in two components corresponding to large scale and small scale variations. In practice the large scale velocity model component can be estimated accurately but the small scale component cannot. Therefore wavefield reconstruction does not completely are perturbed by artifacts. There are two ways to address this problem: improve wavefield reconstruction by estimating more accurate velocity models and image using conventional techniques or reconstruct wavefields with conventional methods using
