Listen to the drill bit

“Our runs are getting shorter and shorter…” That’s what Harrie and Nick from Aurora Drilling Optimisation Services were told by the Shell team that was drilling a deep onshore exploration well in Libya about 15 years ago. They helped design…

Benchmark your geosteering skills

For geosteering geologists, few experiences can replicate the pressure of making critical decisions while a well is being drilled. The 2026 Geosteering World Cup (GWC’26) puts those skills to the test in a global, competitive environment and gives geologists a…

“Oh, look! Oil everywhere…”

What seems like an oil seep on a rock face, especially from a distance, can equally be the result of chemical weathering. When these types of rock coatings, which can be found across a wide range of settings, are misinterpreted…

An imperial testing facility

“It was a $37 M donation from Imperial Oil, the largest to an educational institution in Alberta’s history,” says Gerald Desrochers when we meet for the lab tour he invited me to on a Thursday morning in May. Just over…

Mediterranean eyes on Greece as deepwater drilling approaches

The exploration hunt for hydrocarbons in Greece started in 1938 with the drilling of shallow wells. After a post-war lull, the passage of Greece’s first comprehensive petroleum law in 1959 drew immediate international attention, prompting Esso to secure exploration permits.…

Exploration drilling programme in Greenland postponed and slimmed down

Earlier this year, we reported on a planned two-well onshore exploration campaign to be carried out by Greenland Energy on Jameson Land, in the east of Greenland. At the time, the expectation was to commence drilling in July already, targeting…

Decommissioning and discovering at the same time

The Marlim field was discovered in 1985, on the back of the first proper exploration drive to test the potential of Brazil’s deepwater Campos basin. Oil was found in Oligocene post-salt sands, mostly thanks to a pronounced seismic anomaly. The…

The geological context of the North Cleopatra block

A few days ago, it was announced that the Velox-1X well, drilled in the North Cleopatra block offshore deep-water Egypt by Shell and partners, hit oil. The well, which was drilled to 6,000 m below sea level, is located in…

Deepwater’s playbook for delivering growth

Deepwater production remains a core part of the long-term energy supply mix. While production from conventional onshore and shallow-water assets is expected to remain broadly flat under our base case, Welligence estimates that global deepwater oil production will grow from…

Why dual-phase systems demand a new assessment approach

Various work-arounds attempt to compensate for these limitations, but each introduce their own artefacts. A common approach is to treat gas as a failure by assigning a “gas risk” and evaluating only oil scenarios. Another merges the risked and success…

Why amplitude-supported prospects are not the silver bullet we are led to believe

“When you don’t see a scale bar at a seismic section that shows a nice bright spot, you should be scared”, says Ian Longley from GIS-Pax in a video in which he shares his experience with amplitude-supported prospect mapping. “We…

The increasing importance of DHI’s in the Rotliegend play of the Southern North Sea

It sounds odd, bearing in mind the quality of broadband seismic data available these days: unlocking an offshore gas province without using seismic DHI’s to de-risk exploration drilling. Yet, that is what happened in the Southern North Sea, where the…
