PGS has released final 3D Geostreamer data for the 4725 m2 and 8250 km2 surveys covering deepwater blocks in the Campos Basin offshore Brazil. The data covers areas offered in Brazil’s 17th licensing round, which is scheduled for 7 October.
TTI PSDM products (KPSDM, RTM) products are available over Round 17 blocks C-M-279, 348, 415, 483, plus partial coverage of 212 and 549. Fast-track PSDM data is available over block C-M-481. As previously announced data is also available for blocks C-M-350, 417, 485.
These full-integrity and fast-track products from PGS’s Campos Deepwater GeoStreamer X multi-client 3D programme provide the only 3D data in this area for Round 17 acreage evaluations, claimed PGS.
‘The outer Campos Basin remains an under-explored region, historically due to attention given to the significant presalt discoveries in the adjoining Santos Basin. Attention has returned to Campos Basin, with final investment decision announcements on BM-C-33 presalt (analog) discoveries, numerous Campos Basin drilling permits, and encouraging new field wildcat drilling results, including including the recently announced hydrocarbon shows reported in the Urissane and Mairarê wells,’ said John Cramer, PGS Brazil area manager.
Despite the global pandemic, PGS has now acquired more than 15,600 km2 of GeoStreamer long offset (10 km) seismic and marine potential field data, reprocessed the orthogonal legacy seismic data to perform multi-azimuth processing to enable optimal imaging of the presalt and has also produced 3D fast-track TTI PSDM products covering the outer Campos Basin Round 17 blocks.
‘These new 3D fast-track TTI PSDM products are now illuminating the numerous under-explored plays in this region, which could not be achieved with the limitations of legacy 2D seismic,’ added Cramer. ‘In addition to the traditional presalt plays targeting fractured carbonate reservoirs (build-ups, microbalite platforms) and coquina deposits in a lacustrine setting, we are also observing potential subsalt plays with potential A-C-T sediments underlying allochthonous layered evaporite (salt) in the outer Campos Basin. The available 3D Fast Tracks and gravity/ magnetics data, as well as multi-azimuth full integrity products, will provide reliable seismic imaging for exploration risk mitigation and potential drilling hazard assessment in this emerging deepwater exploration arena.’
