How the threat of military conflict created a successful helium storage project

July 5, 2024

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

Molly Turko - Devon Energy

May 19, 2024

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

Henk Kombrink

May 15, 2024

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,…

Are we moving into the age of the pore space paradox?

Whilst the people at E3 Lithium in Canada will no doubt support the road to Net Zero, they were not very pleased to see the company Enhance receiving a permit…

The vast brushlands of West Texas and New Mexico hold a miracle

Ted Cross - Novi Labs

March 15, 2024

Nestled in the vast brushlands of West Texas and New Mexico, the Permian Basin quietly outstrips the oil production of countries like Iraq, Iran, or Canada, a fact that often…

Rejuvenating legacy seismic for screening carbon storage sites in the Gulf of Mexico

Neville Brookes, Ravi Kumar, Gregor Duval and Simon Otto - CGG

March 11, 2024

A major challenge in the US Gulf of Mexico is transforming disparate public datasets into a quality-controlled database. CGG has successfully created and used a database for its Storage Play…

Don’t forget to look deeper

Molly Turko and Alex Biholar - Devon Energy

March 5, 2024

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

Molly Turko, Cameron Thompson and Kourtney Brinkley - Devon Energy; Julia Gale and Sara Elliot, Bureau of Economic Geology

February 1, 2024

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?

Henk Kombrink

January 12, 2024

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

Elliot Yearsley

October 18, 2023

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…

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

Dr. Molly Turko, Devon Energy

September 12, 2023

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…
