Although the MWT method was already applied to synthetic data, the synthetic data application leads to a development of a hybrid method between waveform tomography and the salt flooding technique commonly use in subsalt imaging. This hybrid method can overcome a convergence problem encountered by inversion with a traveltime velocity tomogram and successfully provides an accurate and highly resolved velocity tomogram for the 2D SEG\/EAGE salt model. In the application of MWT to the field data, the inversion process is carried out using a multiscale method with a dynamic early-arrival muting window to mitigate the local minima problem of waveform tomography and elastic effects. With the modified MWT method, reasonably accurate results as verified by comparison of migration images and common image gathers were obtained. The hybrid method with the salt flooding technique is not used in this field data example because there is no salt in the subsurface according to our interpretation. However, we believe it is applicable to field data applications.<\/jats:p>","DOI":"10.1190\/1.3507237","type":"journal-article","created":{"date-parts":[[2010,12,13]],"date-time":"2010-12-13T18:02:45Z","timestamp":1292263365000},"page":"R129-R136","source":"Crossref","is-referenced-by-count":41,"title":["Applications of multiscale waveform inversion to marine data using a flooding technique and dynamic early-arrival windows"],"prefix":"10.1190","volume":"75","author":[{"given":"Chaiwoot","family":"Boonyasiriwat","sequence":"first","affiliation":[{"name":"1Formerly at University of Utah, Department of Geology and Geophysics, Salt Lake City, Utah, U.S.A., presently at King Abdullah University of Science and Technology, Division of Physical Science and Technology, Thuwal, Saudi Arabia.
