TGS' offerings provide unparalleled value by delivering high-quality, comprehensive regional datasets, including both streamer and ocean bottom node (OBN) data, which is crucial for imaging complex subsurface structures, especially in deepwater environments. This advanced data enables enhanced exploration by more accurate prospect identification,
pre-drill estimations and risk reduction as well as more accurate reservoir characterization and life-of-field subsurface analyses. TGS’ data and insights help operators make informed decisions and optimize resource extraction in the region's challenging geological conditions.
A seismic profile (with velocity model overlay) in the Mississippi Canyon area (Fusion reprocessing) comparing a subsurface image and velocity model produced using just wide azimuth streamer data versus a subsurface image and velocity model utilizing Long Offset OBN data and Dynamic Matching Full Waveform Inversion (DM FWI) combined with wide azimuth streamer data. Long offset OBN data provides additional deep diving refracted energy utilized by DM FWI to develop a more accurate velocity model and thus significantly improved subsurface image.
