Campos Deepwater GeoStreamer X 3D GeoStreamer (In Processing)

Modern GeoStreamer and reprocessed legacy orthogonal data to illuminate the DW Campos presalt play
Website Map for Survey Campos Deepwater-1 MC3D
Campos Deepwater GeoStreamer X satisfies the industry’s demand for accurate seismic imaging of the presalt hydrocarbon plays offshore Brazil and delivers the most geologically sound dataset to date. It mitigates exploration risk and provides a reliable seismic foundation to pursue new opportunities.
The Brazil presalt play fairway is a focus for many companies. Proven reservoir potential is present within the microbiolite and coquinas formations/structures, which contain large hydrocarbon accumulations. Brazil's production from presalt continues to rise.
This north-south azimuth long offset data will be instrumental in extending the presalt play north into the Campos Basin. Continuous broadband Kirchoff/RTM PSDM data are available to address the presalt reservoir in depth to save drilling costs.
