Uncertainty – the most important result of basin modelling

David Rajmon, Consulting Geologist
I have long wanted to write about uncertainties in basin modelling. Despite their general acknowledgement, they are commonly underestimated due to various biases and psychological pressures. Explorationists sometimes live in…

Data is not the new oil

Henk Kombrink
“Deeply misleading”, that’s how Thomas Halsey describes the commonly cited phrase “Data is the new oil”. At least when it comes to data held by the upstream industry. The main…

Peat: So hot right now

Henk Kombrink
“The offshore wind sector is still very much a geotechnical exercise”, I was told recently by someone with knowledge on the matter. “But that model is due an update.” Despite…

A frontrunner in deep-sea minerals

Ronny Setså
The Norwegian deep-sea mineral community closely followed the talks from Nagase Kunpei and Kiyotaka Orita of the Japan Organization for Metals and Energy Security (JOGMEC) during the Deep Sea Minerals…

Seeing around OBM

Henk Kombrink
Geochemical analyses focused on characterising oil are frequently challenged by contamination with oil-based muds (OBM). This renders the results either uncertain or in some cases unusable, particularly in solvent extraction…

Nodules may indeed be “battery rocks”

Ronny Setså
Nodules were originally termed “a battery in a rock” by The Metals Company (TMC) to convey to the public the need for deep sea minerals for the green shift. Polymetallic…

The rise of production geology

Raffik Lazar, GeomodL International
Before anything, let’s clear the water: Production geology is not a cross-over between the cinema industry and our good ol’ geology. Production geology refers to unravelling the geological intricacies in…

Using seismic velocity to derisk oil exploration

Martin Essenfeld and Rafael Sandrea
In a recent GEO EXPRO article, we developed a field-based approach to identify natural gas prospects directly from seismic surveys. The gas fields are straight up. If the p-wave velocities…
