TGS starts São Tomé and Príncipe 2D seismic reprocessing project
  • TGS launched a São Tomé and Príncipe offshore 2D PSDM seismic reprocessing project with the national petroleum agency ANP-STP.
  • Scope covers 14,651 km of 2D seismic lines from four surveys acquired in 1999-2005, targeting a step-up in subsurface imaging quality.
  • Work applies updated processing, including elastic full waveform inversion velocity building and prestack depth migration, to improve depth positioning in complex geology.
  • A priority set of lines is due within seven months; full deliverables are expected in Q3 2027.
  • Project is supported by industry funding, aimed at improving prospect assessment ahead of future licensing activity.
