2D & 3D Seismic Data Reprocessing

Data Reprocessing

Searcher specialises in reprocessing public domain land and marine 2D and 3D surveys by sourcing the field tapes and support data to conduct full broadband PSTM or PSDM workflows using all available modern processing techniques.

Basin wide multi-vintage processing yields a considerable uplift in data quality at a fraction of the cost of new acquisition and often has the additional benefit of providing velocities, gathers, angle stacks and associated AVO products which may not have been produced at the time of acquisition.

Public domain 2D and 3D surveys are often small, partly overlapping datasets that vary widely in quality, character and vintage. The resulting 3D UltracubeTM and 2D SuperTieTM  projects consists of high quality reprocessed data and are a very cost effective way to significantly improve the data quality and area of effective coverage for exploration at the regional or prospect scale.

Through our partnerships with leading service providers we have the capabilities to offer land and marine 2D, 3D and 4D processing solutions to suit any geological setting.
