Angolan Kwanza Basin – expanding proven opportunities
Kwanza Basin – a pre-salt success story? Historically, exploration activity has focused on the prolific Lower Congo Basin in Northern Angola, concentrating on the post-salt Upper Cretaceous and Tertiary reservoirs.…
Maximising the potential of seismic expressions
Spectral decomposition methods are widely used to highlight geological features according to their frequency content. However, the frequencies characterising the targeted event might vary spatially, which complicates their extraction as…
Illuminating the complex geology of the UK Faroe Shetland Basin
Through the integration of legacy seismic data, PGS’s Faroe Shetland Basin Vision product assists companies in their UK 33rd Round applications.
The striking similarities between Namibia and Brazil’s conjugate margins
Regional seismic lines indicate that the Pelotas Basin in Brazil contains the same play ingredients as the Orange Basin in Namibia where the Venus discovery was recently made.
Sudan’s Red Sea oil
The Sudanese Red Sea is one of the world’s most exciting underexplored passive margins. Here, we show how legacy 2D seismic reveals a stunning array of super-giant syn-rift plays in…
Adapting conventional E&P workflows to scale up hydrogen and helium exploration
Natural hydrogen and helium exploration is booming worldwide. The combined production of hydrogen, helium and carbon dioxide in the Earth’s subsurface provides alternative resources that could revolutionize the path to…
