Finding deep sea minerals with oil and gas technology

March 22, 2024

“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

Henk Kombrink

March 20, 2024

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…

Andrew Garioch from Well-SENSE talks us through the use of fibre-optic technology for well intervention work

Can a seal fail?

David Rajmon

March 8, 2024

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?

Henk Kombrink

February 26, 2024

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

Mariël Reitsma and Henk Kombrink

February 20, 2024

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…

Seismic velocity – A strong identifier of gas prospects

Martin Essenfeld - EGEP Consultores SA and Rafael Sandrea - IPC Petroleum Consultants

February 12, 2024

P-wave velocity (Vp) is an essential parameter for constructing seismic velocity models for geophysical exploration data, and porosity is the single most important factor affecting it, along with the type of…

When will the first prospect be drilled that was identified and de-risked through the use of AI?

Henk Kombrink

January 31, 2024

There is a buzz around artificial intelligence (AI). With routine tasks being increasingly taken over by machines, to the point that they are better trained than the human eye, when…

“It is important to embrace what matters in other subsurface realms”

Rodney Garrard

January 23, 2024

“Having worked in oil and gas for years, I was convinced I knew how to drill a well”, Rodney Garrard says. “Then I moved to Switzerland to join NAGRA, the…

The future lies in low-perm reservoirs – not only in the desert but possibly in deep-water too

Henk Kombrink

January 19, 2024

We received quite a few comments on our short story about the commencement of tight gas production from the Ghawar field in Saudi Arabia. Thanks to that, there is an…

What moves a grain?
