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…
The economics of geothermal pumped well power projects
Geothermal pumped well projects provide power to the grid at a contract price and terms negotiated with the power off-taker. This can vary significantly from country to country, but as…
Textbook geology
This panoramic photo shows the El Gordo Anticline plunging in the subsurface towards the right of the image where, unseen, the El Gordo Diapir crops out. The El Gordo Anticline…
Natural fracture networks are not created equal
Natural fracture networks are not created equal. In a tight reservoir, they may enhance the permeability and give production an upside. In a porous reservoir, a natural fracture network may…
Revealing a promising new play concept in the Salar Basin, offshore Canada
Joint PGS/TGS MultiClient data library. The study area is located in the Salar Basin. The South Bank 3D survey is shown in orange. Estimating reliable earth properties using PGS Ultima…
Keeping an eye on the Cuban part of the GOM
The island of Cuba has a rich history of oil and gas exploration, dating back as far as the 1860s when commercial discoveries of heavy oil were found. The first…
Doing it differently
Approved in 2002, the Yucca Mountain Nuclear Waste Repository in Nevada, US, looked to become the country’s final destination for high-level radioactive waste for quite a few years. Until 2011,…
CO₂ leakage out of a reservoir should be accepted as a risk
Rather than telling people that no CO2 will ever leak from a subsurface reservoir, geoscientists should rather use their expertise to explain that there are always risks associated with drilling…
Using old wells as gravitational energy storage devices
The ticket item in the energy transition is the efficient buffering of energy in order to overcome the intermittent nature of solar and wind. Old wells can help with that,…
Leslie Kimberlite core
The history of diamond exploration in the Northwest Territories began in 1981 with Charles Fipke and Stewart Blusson sampling the Mountain Diatreme in the Mackenzie Mountains. While this prospect did…
Directional drilling is going Wild
Twitter can be a good source of information as to what is going in the oil and gas sector, especially in the US. There are a few people from the…
