PGS has released the data on its Campos Deepwater GeoStreamer X survey over the emerging play in the outboard Campos Basin, offshore Brazil.
PGS has released the data on its Campos Deepwater GeoStreamer X survey over the emerging play in the outboard Campos Basin, offshore Brazil.
The new dataset targets 14,500 km2 in the Campos Basin, including open acreage offered in the 17th Bidding Round; presalt open acreage adjacent to the Albacora and Marlim Leste fields and areas acquired and under contract in the 14th Bidding Round, with drilling operations underway to test large presalt structures.
PSDM products now available include Kirchhoff, Beam, and RTM interpretations. The GeoStreamer X project was acquired with 10km-long offsets to improve depth velocity modelling accuracy of the post-salt, salt, and presalt sections.
Ramform Titan acquired the 6500 km2 Phase-1 area, towing the largest seismic spread ever offshore Brazil: employing a 14 x 100 x 10,050 m configuration.
The new Campos Deepwater GeoStreamer X acquisition overlays existing multi-client 3D seismic data from PGS. This was reprocessed in parallel and completed in August. Incorporating the new acquisition with 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.
Deepwater open acreage to be offered in the upcoming 17th Bidding Round can be analysed on the newly released fast-track dataset.
Full-integrity PSDM products will be available in Q2 2021, along with gravity and magnetic data for regional basin analysis and GeoStreamer data.
Fast-track data is available now for presalt open acreage, said PGS. PSDM products will be available in Q1 2021 and the multi-azimuth products will include ~3000 km2 of TTI Kirchhoff and both single and multi-azimuth RTM (45Hz) PSDM products.
John Cramer, sales and services area manager for Brazil, said: ‘We successfully completed the acquisition of the first phase of this programme despite the challenges caused by the global pandemic. The fast-tack products are ready now and we will have full-integrity depth products available prior to the Brazil 17th Bidding Round in 2021. In addition, we will have the first full-integrity GeoStreamer X products available over open presalt acreage in Campos in Q1 2021, and we hope to nominate these blocks for upcoming Presalt Sharing Rounds.’
Ramform Titan has now completed her first-ever yard stay and will be heading back to Campos to acquire an additional 8000 km2 on this programme. PGS will offer additional fast-track products over further 17th Round blocks prior to the round.
