Where does it come from?
The origin of North Sea injectites is still under debate. John Wild, ex ExxonMobil, advocates pre-Tertiary beds as “source rocks”.

A Time-Saving Taxonomic Tool
A new online taxonomy database has proved invaluable for both industrial and academic biostratigraphers. Researchers from University College London (UCL) have earned high praise for the money- and time-saving capabilities…
Codes and Ciphers – PART II
Guest Contributors: Johan O. A. Robertsson and Dirk-Jan Van Manen (ETH Zurich, Institute of Geophysics). Editors: Lasse Amundsen and Martin Landrø. Truth is ever to be found in simplicity, and…
EOR, Local Skills Development and Sustainability
Multidisciplinary interaction and local skills development proved critical when analysing scenarios for advanced chemical EOR in a Sudanese field, thus enabling future sustainability for the vital Sudanese petroleum industry. Following…
Codes and Ciphers – PART I
Decoding Nature’s Disorder Information is the resolution of uncertainty. Claude Shannon. Talk clearly and not so far-fetched as a cipher. Medieval – origin unknown. In many languages the word ‘cipher’…
Searching for Stratigraphic Traps
Historic drilling and production data can be used to enhance exploration strategies focused on stratigraphic and subtle combination traps. Searching for Stratigraphic Traps Stratigraphic and Subtle Combination Traps. (Allan et…
Augmenting Seismic in Challenging Resource-Rich Areas
Just as 3D seismic improved oil and gas exploration, new technology is helping identify oil and gas resources in high definition in areas of permafrost, volcanic cover and heavy oil.…
Supercomputers for Beginners – Part IV
Quantum Computers God does not play dice with the universe. Albert Einstein The 2012 Nobel Prize in Physics was awarded to Serge Haroche and David Wineland for Quantum Entanglement, which…
A Cleaner Future for Heavy Oil Extraction
Climate change has raised questions about the future of carbon-intensive industries, including the development of unconventional oil reserves. But emerging technology from Canada is proving that heavy oil extraction can…
Broadband Seismic Technology and Beyond PART VII: CGG’s BroadSeis – A Change of Thinking
As geophysicists, we learnt and believed that seismic deghosting through ghost notches in pressure-only recordings was impossible when the sensors were deep. CGG changed that way of thinking. Instead of…
Broadband Seismic Technology and Beyond PART VI: Towards a Ghost-Free Solution
PGS launched the ‘ghost-free’ GeoStreamer GeoSource solution in 2011: a time- and depth-distributed source using sub-sources operated at specific depths and time delays, attacking the source-ghost effect in seismic data.…
Gravity for Hydrocarbon Exploration
Can an unexplored sedimentary basin be unravelled by gravity? How can gravity in cross-disciplinary workflows estimate the base of salt domes and gas saturation in shallow sedimentary traps ? Read…
