Nigeria MegaSurveyPlus (In Processing)

10 700 sq. km of 3D data kick-starts reprocessing efforts to create Nigeria’s first MegaSurveyPlus
Website Map for Survey Nigeria MSP
The MegaSurveyPlus concept aims to revitalize the Nigeria MultiClient data library through reprocessing of 3D data from field tapes. Data will be available in Q4 2022.
Extensive MegaSurveyPlus 3D data gives an expanded and consistent regional geological perspective. Pre-stack PSTM products can be used for regional interpretation and AVO analysis, with full-stack products giving a greater understanding of the distribution of play fairways and migration pathways.
Modern techniques including optimized denoising algorithms and a full deghosting sequence will improve data bandwidth and signal-to-noise ratio. Application of a multiple attenuation process also leads to enhanced image integrity by eliminating complex multiples.
