Titanic effort in ultra deep waters off Newfoundland
ExxonMobil, with partner QatarEnergy, is drilling the Persephone (C-54) wildcat offshore Canada’s Labrador and Newfoundland coast. This new frontier wildcat is testing a number of conventional clastic reservoirs in rifted…
Shallow geothermal in Canada – A deep penetration in the geo-energy market
This is the last out of three articles in the shallow geothermal series. In previous articles, we discussed shallow geothermal drilling technology, the market, and the role of the subsurface…
How the threat of military conflict created a successful helium storage project
Storing non-hydrocarbon gas in depleted oil and gas fields is a hot topic, whether it is permanent storage of CO2 or temporary storage of H2 produced by excess wind energy.…
Riedel shears, my favorite kinematic indicator
Riedel shears are commonly the first set of subsidiary faults we see prior to the breakthrough of a master fault. They form systematically at an acute angle (~10-20°) to the…
Producing shale gas through the injection of CO2
If the people living in New York’s Southern Tier thought that shale gas production is not going happen in their backyard because of the ban on using water for fracking,…

As oil and gas geoscientists, we often focus on the reservoir we are targeting. Seldom do we consider what might be happening deeper, especially in basement rocks. However, what happens…
Analysing a hydraulically fractured horizontal core to assess refrac candidates
Is a refrac worth the investment? That is what we investigated in an extensive study. A key piece of data in the study included a horizontal core adjacent to a…
After four years of production, what is the verdict?
Whilst drilling of Eavor’s landmark geothermal closed-loop drilling project in southern Germany has reached the deepest point this week, the company also released a report summarising the past four years…
