PGS has completed acquisition of the first two parts of a new long-offset GeoStreamer-X seismic survey in the Campos Basin, offshore Brazil. The majority of the coverage so far targets areas for the Brazil 17th Bidding Round scheduled for early 2021. Fast-track PSDM products will be available in Q3.
The survey, acquired by the vessel Ramform Titan, towed the largest acquisition spread ever deployed in Brazil with a 14 x 100 x 10050 m, dual-sensor, dual-source configuration. Ramform Titan completed acquisition of the 6500 km2 area ahead of schedule, with an average production of 80 km2 per day.
PGS’ Campos Deepwater GeoStreamer X programme targets Campos Basin presalt open acreage areas acquired in the 14th Bidding Round, and open acreage offered in the 17th Bidding Round.
The survey will cover an area of approx. 14,500 km2 and overshoot PGS’ existing orthogonal MC3D currently being reprocessed in parallel.
This new GeoStreamer X project will provide 10-km long offsets to improve depth velocity modelling accuracy of the post-salt, salt and presalt sections, facilitated by the use of PGS’ Full Waveform Inversion (FWI) technologies.
These additional offset data also promise added angle-range for presalt seismic amplitude analysis and reservoir characterization. Incorporating the newly reprocessed orthogonal MC3D datasets (8 km offsets) will provide a multi-azimuth solution, enabling improved illumination of the subsurface structures found within the presalt plays in this portion of the Campos Basin.
The western part of 2020 acquisition on the Campos Deepwater GeoStreamer X survey targets presalt open acreage. The multi-azimuth products will include ~3000 km2 of TTI Kirchhoff and both single and multi-azimuth RTM (45 Hz) PSDM products and the broadband reprocessing of the underlying orthogonal datasets. Final PSDM products will be available in Q2 2021.
The eastern portion now completed targets the deepwater open acreage to be offered in the upcoming 17th Bidding Round. Fast-track PSDM products will be available through Q3 2020, prior to the 17th Bidding Round. Final PSDM products will be available in 2021, including KPSDM and 45 Hz RTM.
In addition, PGS will be offering, gravity and magnetic data for regional basin analysis, as well as standard GeoStreamer field deliverables.
Meanwhile, PGS said that it expects to report second quarter segment revenues of approx. $138 million. Contract revenues ended at approx. $31 million. multiclient pre-funding revenues were approx. $66 million, from a capitalized cash investment of approx. $64 million, while multiclient late sales were approx. $36 million.
