Oslo – October 15, 2026 -- TGS has secured multi-client rights from state agency PetroGuin to reprocess more than 11,000 km2 of JAAN 3D seismic data across Guinea-Bissau, with final products due in Q4 2027.

TGS builds on 2019 reprocessing with new imaging tools

The agreement builds on the parties' previous 2019 PSDM reprocessing. TGS will apply elastic dynamic-matching full waveform inversion (E-DMFWI) and Kirchhoff pre-stack depth migration (KPSDM). The company expects a significant uplift in image quality compared with the existing data.
