Seeing around OBM
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…
Worldwide
The Low Earth Orbit satellites are coming
Until very recently, seismic acquisition companies only “saw” the data resulting from a marine survey when the vessel returned to shore. Of course, basic quality control of the data always…
Nodules may indeed be “battery rocks”
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
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…
Shallow geothermal in Canada – A deep penetration in the geo-energy market
This is the last out of three articles in the shallow geothermal series. In previous articles, we discussed shallow geothermal drilling technology, the market, and the role of the subsurface…
Using seismic velocity to derisk oil exploration
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…
Net energy matters
Whilst these sources have a supporting role to play in the energy system, the majority of energy sources for powering the world should be high density, low emissions, low land…
Getting increasingly complicated reservoirs to surface
“In a way, we have benefitted from the slowdown in drilling activity”, says Steve Rait from Reservoir Group when we meet at the company’s coring headquarters just north of Europe’s…
Seismic ocean bottom node acquisition without ROV
Guided by industry demand for improved efficiency and reduced costs for the acquisition of sparse node grid seismic and 2D transects, Allton was led to research and develop an innovative…
Working in oil and gas requires resilience
“If the oil price drops even further, it’s game over for the North Sea”, said a colleague in September 2014 when the big oil price tumble had just begun. I…
Shallow clastic targets and electro-magnetic surveys – a good match
“The most interesting test for our technology is the upcoming drilling campaign near the Wisting discovery in the Barents Sea”, said Martin Hansen, Daniel Baltar and Friedrich Roth from EMGS…
The forgotten value of (seismic) tapes
“I’m probably the only tape machine specialist left in northwest Europe”, says Egil Simones from ET Works when we meet at the EAGE Conference in Oslo this week. Egil is…
