Make geomodelling grAIt again?
Not too long ago, reservoir modelling came at a time when the industry was relying on super capable draftsmen/women who could literally translate the mind of geologist into paper. Resources…

Mixing models madness
With most prospects, multiple trapping elements contribute to the potential size of the discovery. For instance, a prospect can be a 4-way at the top of the closure, but may…

PREVENTING BLOWOUTS IN GEOTHERMAL WELLS It is not only only oil and gas wells that can experience blowouts. The same can happen when targeting hot water or steam, as a…
The structural risk of vertically exaggerated cross-sections
It is quite common for seismic lines to be displayed with high degrees of vertical exaggeration. However, vertically exaggerated sections can skew the true geometry of a basin and provide…
Shallow gas in production and decommissioning
This is the third and final article in the article in the Shallow Gas series, brought to you by Francis Buckley. Read the previous articles here: Shallow gas: How to…
Shallow gas as a resource
This is the second article in the Shallow Gas series of three, brought to you by Francis Buckley. Read the first article here: Shallow gas: How to better map the…
Shallow gas: How to better map the risk?
Shallow gas has long been known as a drilling hazard. However, the increasing costs of powering offshore production facilities, the problems associated with decommissioning, and the contribution of natural and…
Is there a coal exploration industry?
If oil and gas are dirty words when talking about energy, it is even more dangerous to mention the c*** word. However, despite the rapidly rising share of renewables in…
How do recent geoscience graduates experience the job market?
During panel debates, where industry-stalwarts share their visions on how the energy sector is evolving, it is often said that the job market for geoscientists in the energy sector will…

Helium-3 – Should we go to the Moon to get it, or to Australia?
Helium has two stable isotopes: Helium-4 (4He), which makes up 99.9998% of helium on Earth, and helium-3 (3He), present in absolute trace amounts. Whereas 4He forms continuously as a result…
How to identify fluid migration with 1D models and temperature data
One revealing experience occurred while I was working in a basin offshore Thailand. I only had temperature data from several wells. Once a 1D model was built for each of…
