Exploring CO2 storage efficiency: striving for clarity
Prior to building a full 3D model of a carbon store, the mass of CO2 that can be stored in a reservoir can be calculated by multiplying the pore volume by the…
Subsurface Storage
Are Sleipner and Snøhvit calling into question the long-term viability of CCS?
It appears that the Institute for Energy Economics and Financial Analysis (IEEFA), headquartered in Ohio US, is overly critical towards the future of Carbon Capture and Storage projects. The Institute…
A star to enable safer CO₂ storage
It forms a wonderful pattern, NORSAR‘s new array NORFOX, which is buried deep in the forest on Løten, Norway. However, it is not particularly visible. Some long tracks and a…
Doing it differently
Approved in 2002, the Yucca Mountain Nuclear Waste Repository in Nevada, US, looked to become the country’s final destination for high-level radioactive waste for quite a few years. Until 2011,…
Dutch flagship CCS project given the go-ahead in court
More than 1000 people listened to the online broadcast of a hearing that lasted for about 3 minutes. There was something important at stake; the future of carbon storage in…
CO₂ leakage out of a reservoir should be accepted as a risk
Rather than telling people that no CO2 will ever leak from a subsurface reservoir, geoscientists should rather use their expertise to explain that there are always risks associated with drilling…
Using old wells as gravitational energy storage devices
The ticket item in the energy transition is the efficient buffering of energy in order to overcome the intermittent nature of solar and wind. Old wells can help with that,…
Retraining for CCS projects
Understanding the technical and operational risks in each component of the transport and storage system is rudimentary to CO2 leakage prevention and system performance optimisation. For instance, injection well issues…
Spinning the CCS project wheels – it’s time to change gear!
As I write, CO2 is being injected from the Nini platform in the Danish North Sea as part of Project Greensand, the world’s first cross-border offshore CO2 storage project facilitated…
Boring? Maybe not so boring!
“It’s the details that always bite you in the end”, said Ronny Parr from the North Sea Transition Authority to the audience at SPE’s Seismic 2023 Conference in Aberdeen yesterday.…
Producing more from Norwegian oil fields without impacting the climate
“The answer is a definite yes”, says Ole Gunnar Tveiten, geologist at AGR, regarding the possibility for Norway to maintain oil production in the years to come and at the…
The challenge at Gorgon
“Every CO2 project will have its unique challenges”, said Chris Stavinoha from Chevron during his presentation at SEAPEX last month. And as he explained during his talk, Chevron’s Gorgon CO2…
