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…

What could be behind the downgrade of Shell’s deep-water discoveries in Namibia?
This week, Namibia’s petroleum commissioner Maggy Shino announced that Shell has thus far discovered 200 million barrels of recoverable oil at Graff and 300 million barrels of recoverable oil at…
More wells
High-impact New player MCF will drill two high-impact wells in Germany in Q1 2024. One will be a development well in the Lech area Bavaria, Germany. A previously drilled well…
The future lies in low-perm reservoirs – not only in the desert but possibly in deep-water too
We received quite a few comments on our short story about the commencement of tight gas production from the Ghawar field in Saudi Arabia. Thanks to that, there is an…
Ghawar keeps on going
In November last year, Aramco announced that it produced its first unconventional tight gas from the Ghawar South project, producing up to 300 mmscf/day of gas and 38 kbpd of…
Lots of activity but limited resource growth
Every year in January, the Norwegian Offshore Directorate – which until the turn of the year was called the Norwegian Petroleum Directorate – summarizes the activities on the Norwegian continental…
The future looks bright for the world’s fourth-youngest country
Timor-Leste was quick to capitalise on its oil and gas resources after in became independent in 2002. In the same year, a treaty was signed with Australia for a Joint…
Are the glory days over?
As the magazine’s last issue of the year is now being printed, I have a bit of time to reflect on some of its content. That’s the advantage of being…
Can we get more comfortable with uncertainty?
Unfortunately, diligent and scientific handling of subsurface uncertainty is rarely undertaken. Hesitance to embrace uncertainty often derives from time, data and budget constraints, limited interdisciplinary understanding, accompanied by claims of…
Why did it take so long to develop Rosebank?
Rosebank was discovered in 2004 by Chevron and partners DONG, OMV and then StatoilHydro. The reservoir quality of the Paleocene/Eocene Colsay Sandstone Member was shown to be good (around 20%),…
Production allocation and fluid fingerprinting in conventional reservoirs
Geochemical fingerprinting for production allocation of oil, gas or water is a well-established workflow in conventional reservoirs for both subsurface and topside facilities applications. These methodologies have been in existence…
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…
