Prestack gather flattening using segmental dynamic time warp
Feng Qian, Lin Chen, Feilong Zhang, Guangmin Hu · 2016
This paper proposes a pre-stack gather flattening algorithm using Segmental Dynamic Time Warp. It is able to solve the defect that dynamic time warp (DTW) will break seismic events continuity and also change the overall look of the original seismic gather when moving according to the time shift for each point. The core idea of our flattening algorithm is finding key matching segments (adaptive windows) and its time shift of different pre-stack gathers by segmental DTW, instead of each time point and its time shift by DTW. Therefore we can flatten pre-stack gather while avoiding the caused problems by DTW. Presentation Date: Tuesday, October 18, 2016 Start Time: 10:20:00 AM Location: Lobby D/C Presentation Type: POSTER
