Challenging ground conditions for Norwegian offshore wind
“The ocean bottom conditions on the Norwegian continental shelf are challenging and vary from place to place, so they must be examined in detail”, says Lars Jensen, geophysicist at the…

Eocambrian outcrops and hydrocarbons in Southern Oman
The author took part in a 10-day industry field trip to study the Huqf and younger exposures in 2011, from which many outcrop photos are used to illustrate this article.…
A new global sea-level curve
Traditional long-term eustatic sea-level reconstructions suffer from uncertainty in stratigraphic interpretations of the rock record, which leads to ambiguity. Sea-level reconstructions from plate tectonic modelling are limited in use due…
Cutting data – please handle with care!
“It’s not precise at all, so please handle with care”, is one of the first things Anita Hansen tells me when we meet on Teams. We spoke about working with…
Islands by night or…
In an article we recently published, Olav Walderhaug from Equinor shared his thoughts on the possible presence of a deeply buried gas source rock in the North Sea. The line…
Recognising Key Stratigraphic Markers During Drilling – The Balder Tuff
The Eocene Balder Tuff is an important and widespread stratigraphic marker in the North Sea. For most wells drilled in the area, it sits in the overburden, far away from…
An Exposed Salt Dome
The salt exposed here consists of halites of the Ara Salt, which was deposited around 540 million years ago during the earliest Cambrian. The core of the dome, where the…
The Best of Brae
In Late Jurassic times, an overall north-south trending graben system transected the North Sea as a response to tensional stresses building up in the wider area. The grabens were connected…
Microfossils and the World of Chalk and Chert
Microfossils are those fossils that require a microscope to carry out fundamental identification. They are the fossils of a biologically diverse group of organisms, including microscopic algae, protists, and invertebrates,…
How Does Wet Gas Form?
A study performed by Olav Walderhaug from Equinor, the main outcomes of which he shared with GEO ExPro, shows that out of 50 reservoirs classified as wet gas accumulations, 47…
Palynology reinvented
An old technique re-imagined and reducing uncertainty in CCS sites. Palynology Reinvented Capturing carbon dioxide (CO2) from industrial and power sources and storing it in subsurface geological formations is an…
Seeing the whole picture
During the pandemic, Lyme Bay Consulting took the opportunity to download all the Operator-released 3D seismic data in the UKCS to produce a series of Post-Stack Merged Seismic Volumes covering…
