Brazil Pre-Salt Basins

CGG is your ultimate source for all the data you need for exceptional exploration opportunities in Brazil. We have recently acquired or reprocessed advanced broadband seismic data covering blocks that will be available in upcoming pre-salt bid rounds. CGG's vision is to provide seismic data sets applicable to every phase of the pre-salt evaluation process, by creating over 100,000 km² of contiguous, high-quality, broadband, pre-stack depth migrated data, spanning the prospective Santos and Campos Basins. This is complemented by a further 20,000 km² in Espirito Santo.

Santos VIII

CGG has completed acquisition of Santos VIII, the newest survey in our multi-client program designed to cover the pre-salt area with modern broadband seismic. Santos VIII was acquired using BroadSeis technology and covers an area of 8,037 km², adjacent to Peroba, Pau Brasil and the Constellation/Constellation Extension reprocessing project. This survey is currently being processed in our Rio de Janeiro Subsurface Imaging Centre using full-waveform inversion (FWI). The Fast Track TTI PSDM is now complete and the preliminary migration results reveal impressive structures similar to Saturno.

Santos VII FTSantos VII (Saturno)

The Santos VII BroadSeis survey covers an area of 15,767 km², including the highly prospective Saturno prospect, a major pre-salt opportunity with no 3D coverage to date. It forms a bridge linking the Constellation reprocessed data to the recently reprocessed Pulsar data sets, providing an extensive area of contiguous broadband seismic coverage over the Santos and Campos Basins.

The final TTI PSDM data for Santos VII delivers impressive broadband images of Saturno and the surrounding pre-salt exploration area. This data has been processed using the latest broadband technology and imaged with advanced velocity modeling techniques, including FWI using both refracted and reflected waves.

Polaris Reprocessing

Providing the best quality data to our clients is paramount, so in addition to acquiring new surveys, we have undertaken several reprocessing projects using the most up-to-date processing technology. Polaris, located in Campos Basin, is the latest phase in our expansive multi-client pre-salt program. This reprocessing project will merge 10 different surveys, including Campos II and multiple public domain datasets, and will cover 12,970 km² encompassing the Norte de Brava and Agua Marinha blocks that will be available in upcoming Production Sharing Bidding Rounds. The new Polaris data set will be processed using state-of-the art processing algorithms including advanced 3D deghosting, Interbed Multiple Attenuation (IMA) and velocity modeling techniques including FWI, RFWI and Time-Lag FWI. The data set will deliver superior imaging of pre-salt structures over open acreage with multiple prospects and provide our clients with valuable information to identify potential pre-salt drilling targets. In anticipation of Round 6, a Fast Track TTI PSDM will be available in August 2019 over the Norte de Brava area and the full Fast Track data set will be available in November. Final deliverables will include a TTI RTM PSDM and a TTI Kirchhoff PSDM and both will be available in Q1 2020.

Pulsar Reprocessing

The Pulsar survey is a merge of the southern portion of Campos II and Santos VI-A and B. This project creates a bridge from the Santos to the Campos basins and forms part of a contiguous state-of-the-art broadband data set covering the entire area.

Constellation - Constellation Extension Reprocessing

Constellation is another reprocessing project just southwest of Pulsar that has been extended to create a 44,153 km² data set, which includes the original Cluster Extension. The Constellation projects also use up-to-date processing algorithms, including 3D de-ghosting, bandwidth extension and TTI FWI model-building.

Pre-Salt JumpStart

This is complemented by our Brazil Pre-Salt Constellation JumpStart project which integrates the seismic with all the available well and geological data to provide a single source of information in a consistent easily-accessible format. The well data has been re-calibrated and interpreted using stratigraphy and petrophysics to deliver consistent Formation Description Logs and seismic-to-well ties.

The JumpStart project delivers a thorough report on the petroleum systems of the Santos Basin, with focus on the 'pre-salt', including a dry hole analysis and identification of key risks and success factors. It provides a full structural and stratigraphic interpretation for key horizons, with attributes extracted to map the potential presence of hydrocarbon fluids and reservoir facies, and the final, comprehensive report contains a full prospectivity evaluation with play maps.
