BP has applied a variety of depth migration methods on standard surface streamer data to improve the image. However, the severe velocity discontinuities due to the complex salt which is proximate to the rugged water bottom causes gaps in the illumination of the structure that can not be filled with conventional surface streamer data. In 2004 BP implemented a "first of its kind" marine wide azimuth streamer survey. Depth migrating the wide azimuth seismic data yielded a substantially improved image of the reservoirs. This paper discusses the motivation behind the seismic acquisition redesign and some of the challenges of processing wide azimuth surface streamer data.Permalink: https://doi.org/10.1190/1.2370130FiguresReferencesRelatedDetailsCited bySolving Mad Dog subsalt imaging in two decades: From WATS to OBN to elastic FWIHui Liu, Fran Rollins, Kevin Pratt, Elizabeth Da Silva, Nathalie Mootoo, Tongning Yang, Dorothy Ren, Fei Gao, and Jiawei Mei1 June 2023 | The Leading Edge, Vol. 42, No. 6Joint deblending and source time inversionYangkang Chen, Sergey Fomel, and Ray Abma22 August 2022 | GEOPHYSICS, Vol. 88, No. 1The Wolfspar experience with low-frequency seismic source field data: Motivation, processing, and implicationsAndrew Brenders, Joe Dellinger, Imtiaz Ahmed, Esteban Díaz, Mariana Gherasim, Hu Jin, Madhav Vyas, and John Naranjo4 January 2022 | The Leading Edge, Vol. 41, No. 1References4 February 2021An efficient super-virtual shot encoding scheme for multisource reverse time migrationXiaofeng Jia, Wenyang Chen, and Bin Chen23 November 2020 | GEOPHYSICS, Vol. 85, No. 6Three-dimensional angle-domain double-square-root migration in VTI media for the large-scale wide-azimuth seismic data1 June 2020 | Acta Geophysica, Vol. 68, No. 4Sparse nodes for velocity: Learnings from Atlantis OBN full-waveform inversion testJiawei Mei, Zhigang Zhang, Feng Lin, Rongxin Huang, Ping Wang, and Cheryl Mifflin10 August 2019Overcoming the challenges of a shallow-water sparse wide-azimuth survey to improve deep reservoir imaging in the East China SeaYun Wei, Hua Chen, Senqing Hu, Peipei Deng, Yongdeng Xiao, Srujan Poonamalli, Robert To, Joe Zhou, Jason Sun, Gang Yao, and Yu Jiang31 July 2019 | The Leading Edge, Vol. 38, No. 8Full-waveform inversion for salt: A coming of agePing Wang, Zhigang Zhang, Jiawei Mei, Feng Lin, and Rongxin Huang28 February 2019 | The Leading Edge, Vol. 38, No. 3Reflection and Refraction Seismic Methods19 July 2017Fast simultaneous seismic source separation using Stolt migration and demigration operatorsAmr Ibrahim and Mauricio D.
