Quantitative interpretation is now available from the PGS/TGS 2019 GeoStreamer survey acquired over the northern part of sector NL04-EN in the Orphan Basin, offshore Canada.
A second QI volume, created using data from the partners’ 2018 acquisition over the southern part of the sector, is also available.
The recent North Tablelands and Tablelands surveys cover this highly prospective portion of the south-eastern Orphan Basin.
Many AVO-supported leads have been identified in the NL04-EN sector, including anomalies with low Vp/Vs and low impedance corresponding with structural closure. Two new quantitative interpretation (QI) projects enable a greater understanding of these and the overall lithology and fluid distribution at the reservoir level.
A Full Waveform Inversion (FWI) project over a select area of the Tablelands survey provided improvements to the velocity field, which were then used to drive the QI inversion and prestack depth imaging.
‘The new QI results are striking and should be essential viewing for E&P companies submitting bids on Eastern Newfoundland 2020 licensing opportunities,’ said PGS.
A single, continuous high-resolution seismic dataset was expected to be completed this month, covering both the Tablelands and North Tablelands surveys.
Meanwhile, PGS has announced that from 2020 all vessels in its fleet will share bathymetry information collected using echo sounders with the Nippon Foundation-GEBCO Seabed 2030 project that aims to map the entire ocean floor by 2030.
PGS had already launched an initiative in 2017 to release surplus environmental data from ocean surveys and activities for research on ocean development. Seabed 2030 has already mapped 15% of the ocean floor, doubling its coverage from the 6.4% mapped in 2014.
