16 Oct 2020

PGS reports that PSDM products are now available from the PGS Campos Deepwater GeoStreamer X survey over the emerging play in the outboard Campos Basin. The data targets acreage to be offered in Brazil's 17th Bidding Round, plus presalt open acreage adjacent to Albacora and Marlim Leste fields.

Campos Deepwater Coverage

The new dataset targets 14 500 sq. km in the Campos Basin, including

  • Open acreage offered in the 17th Bidding Round
  • Presalt open acreage adjacent to Albacora and Marlim Leste fields
  • Areas acquired and under contract in the 14th Bidding Round, with drilling operations underway to test large presalt structures.

Fast-track PSDM products are now available and include Kirchhoff, Beam, and RTM products. This GeoStreamer X project was acquired with 10 km long offsets to improve depth velocity modeling accuracy of the post-salt, salt, and presalt sections.

GeoStreamer X Multi-Azimuth Illumination

Ramform Titan efficiently completed the acquisition of the 6 500 sq. km 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 MultiClient 3D seismic 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.

Data for 17th Round Open Acreage

Deepwater open acreage to be offered in the upcoming 17th Bidding Round can be analyzed on the newly released fast-track dataset.

Full-integrity PSDM products will be available Q2 2021, along with gravity and magnetic data for regional basin analysis, as well as standard GeoStreamer field deliverables.

Revealing Presalt Opportunities

Fast-track data is available now for presalt open acreage. Full Integrity PSDM products will be available in Q1 2021 and the multi-azimuth products will include ~3 000 sq. km of TTI Kirchhoff and both single and multi-azimuth RTM (45Hz) PSDM products.

John Cramer, Sales & Services Area Manager for Brazil commented: 'We successfully completed the acquisition of the first phase of this program 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 8 000 sq km on this program. PGS will offer additional fast-track products over further 17th Round blocks prior to the round.
