The global energy sector from a subsurface perspective

North America

The Koloma Enigma

Mariël Reitsma, HRH Geology
The company describes itself as a technology-enabled explora­tion firm that leverages indus­try expertise, proprietary data, specialised exploration tools, and ad­vanced data analytics to facilitate large-scale natural hydrogen production. Backed by…

Sponge clasts in calciturbidites

Text: Henk Kombrink, Photography: Ali Jaffri, Applied Stratigraphix.
At the recent IMAGE Conference in Houston, somebody told me that the Permian Basin in Texas is not only famous for its hydrocarbon resources, but also because the uplifted areas…

Finding big fields by detecting the smallest element

Henk Kombrink
“We are changing the world of explo­ration,” says Denis Krysanov from He­ologic, when we meet on Teams. “I’m now planning on expanding Heologic’s operations in the United States,” he says.…

Decoding slip with tension gashes

Molly Turko, Devon Energy
Tenson gashes are fractures in rocks formed under ex­tensional stress, of­ten filled with minerals like quartz or calcite. These fea­tures are key kinematic indi­cators in structural geology, revealing fault slip…

Sometimes an old well is better than a fancy new one

Mariël Reitsma, HRH Geology
While there is always press around he­lium discoveries, companies that are actually producing it often go unno­ticed. That doesn’t mean they don’t have interesting stories to tell. Ca­nadian-based Thor Helium,…

The tech powering the future of geothermal energy

Jocelyn Brown, Seequent
Geothermal energy, once overshad­owed by other renewables, is entering a new era. Historically, its use depended on rare geological conditions: Underground heat, permeable rock, and natural water supplies — usually…

Cuba – the next hydrogen hotspot?

Henk Kombrink
“I have concluded that this area should not be explored for oil, but for hydrogen instead. And I believe that the potential is colossal,” wrote Marcello Rebora in his email.…

The Athabasca oil sands

Henk Kombrink
Recent governments in Canada have not been particu­larly supportive of the oil industry, which mainly concentrates in Alberta. Some people are even actively contemplat­ing separation from the Canadian federation and…

A subsea tie-back to a subsea tie-back?

Henk Kombrink
The name of the discovery may suggest that it is the most distal find in the Gulf of Mexico ever, but that is not the case. bp’s recently announced Far…

Flame structures

Ali Jaffri, Applied Stratigraphix
Outcrops remind us of the risks of applying a layer-cake approach to correlating well data. Turbidite lobes pinching out, channels abruptly transitioning to floodplain deposits or carbonate platforms only developing…
