Helium – the birth of a new exploration industry
Multiple dedicated helium discoveries have recently been made, but reserves have yet to be proven

A new closed-loop horizontal geothermal well solution
In Europe, deep geothermal heat production for district heating and to a lesser extent district cooling is mainly based on the conventional doublet geothermal well solution. Examples are the wells…
Salt and Grit
“My fascination with geology started with asking myself a question”, says Clara Rodríguez Rondón. “I grew up in Venezuela, in a town called San Juan de Los Morros, in a…
Geomodelling for CCS, a bridge too far?
Traditionally, geomodels are built in a simplistic fashion, taking into account the inherent degree of uncertainty in the input data. Attempting to accurately depict an unseen geological object, often multiple…
The competitive world of coring
Until wireline logging came into swing, cutting core was the most important way to obtain reliable information about the targeted formation. With the advance of wireline logging though, the need…
“In 10 years, nobody would risk installing a subsea well without fibre optic sensing”
It is corrosion resistant, has a long lifetime, no electronics are required downhole, and the “cable” is only a quarter of a millimeter thick. Fibre optic sensing technology has a…
Finding deep sea minerals with oil and gas technology
“With conventional exploration for oil and gas, electromagnetic measurements (EM) are used to map resistivity in prospects – hydrocarbons are more resistive than brines. When we are looking for minerals,…
Deciphering the wealth of data that come from fibre optic sensing
It is corrosion resistant, has a long lifetime, no electronics are required downhole, and the “cable” is only a quarter of a millimeter thick. Fibre optic sensing technology has a…
A dissolvable tool
Andrew Garioch from Well-SENSE talks us through the use of fibre-optic technology for well intervention work
Can a seal fail?
A seal is a rock that has a higher capillary entry pressure relative to other adjacent rocks. The higher the contrast, the greater the hydrocarbon column it can hold. The…
What is the longest well drilled along hole?
Based on a post on social media, in which we asked our followers to name the well with the highest step-out ratio – the ratio between horizontal distance and vertical…
This is the time of subsurface by-products
Speaking to an Aberdeen audience about 10 years ago, Jon Gluyas argued that the North Sea oil business was in essence a water industry. Looking at volumes of produced water…
