PGS Delivers GeoStreamer X Data over Campos Basin Pre-Salt

Final products are now available from the first multi-azimuth swath in PGS’ ongoing Campos Basin program. These new depth products demonstrate the imaging improvements GeoStreamer X data provides in the Brazil pre-salt play.

The ‘X-Factor’
GeoStreamer X offers a step-change in data quality for the complex geological regimes of the emerging Campos pre-salt play, by combining multisensor broadband fidelity with long offset, azimuth-rich illumination. GeoStreamer X acquisition designs are tailored, including sources, streamer spacing, and streamer length to enable more accurate depth velocity model building.

Campos Deepwater GeoStreamer X is an industry-supported MultiClient 3D seismic program with MAZ coverage.

Campos Basin Coverage
This survey combines new and reprocessed legacy data to deliver high-quality, long-offset, MAZ seismic data over the deepwater portion of central Campos Basin.

• Open acreage offered in the upcoming 17th Bid Round
• Open acreage within the pre-salt polygon, adjacent to prolific producing fields
• Held acreage acquired in the 14th and 16th Bid Rounds, with drilling operations underway on large pre-salt structures

When completed, the Campos Deepwater GeoStreamer X survey will cover approximately 17 100 sq. km, extending 3D GeoStreamer coverage beyond the prolific Albacora and Marlim Leste fields, and into the emerging deepwater pre-salt plays, to illuminate the complex geology of the Campos pre-salt targets.

PGS’ Full Waveform Inversion (FWI) driven, depth velocity-modeling of the post-salt, layered evaporate (salt) and pre-salt sections have provided more accurate updates utilizing long-offset MAZ data. Multi-azimuth and FWI-driven velocity modeling have improved both illumination, depth accuracy, and image quality of the subsurface structures found within the pre-salt play. The results will support reservoir characterization work.
