Fast Cycle PreSDM Model Building Using Dense RMO Analysis and 3D Finite Offset Tomography – A Timor Sea Case Study

C020 Fast cycle PreSDM model building using dense RMO analysis and 3D finite offset tomography – A Timor Sea Case Study Abstract 1 We have replaced the classical migration scan methodology by a combination of dense residual moveout (RMO) picking and 3D finite-offset tomography in areas of moderate structural complexity. The objective was a significant reduction in turnaround time for the PreSDM model building with an equal or better final image quality. On a Timor Sea marine streamer dataset re-processing project we found that a reduction of the project duration by a factor greater than two is achievable whilst improving
