Vol. 21

Issue 4

We’re ready to go to Houston! As you may recognise from the front cover, the fourth issue of this year features an artist’s impression of drilling a well in the Gulf of Mexico. Why? Because here, as in many other parts of the world, drilling a little deeper can sometimes result in a surprising find. Our cover story describes a series of those discoveries, which are sometimes serendipitous, but based on recent developments it can also be concluded that some companies have started to systematically explore and produce hydrocarbons beneath existing accumulations. This is the case in China, for example, and in Saudi Arabia.

What else can you expect from this issue? An interview with Sarah Stogner, a lawyer from Texas who has made headlines recently in her efforts to make sure that companies are plugging their Permian Basin wells properly. Her confrontational approach is something not often seen in the industry, and may shake up things a bit!

We also host a great number of seismic foldouts again, taking you from Trinidad via the Gulf of Mexico to Papua New Guinea and back to the UK North Sea!

And, as always, our contributors share their subsurface expertise in a wide variety of columns.

Deep-water Delaware

The featured photo shows a road cut in the Permian (Guadalupian) Brushy Canyon Formation off US Highway 62/180 in the foreground. The west-facing exposure, with the Delaware Mountains in the Read More

The time of deep resistivity

Times are gone that deep resistivity tools are only being used for geo-steering. The inverted data help build geomodels, help estimate net pay thickness away from well data and see Read More

The geoscience of decommissioning

“ Let’s not try to sugarcoat it, it wasn’t always easy”, she continues. “The pandemic unfolded, and taking care of ho­meschooling, a full-time job and completing the university modules on Read More

The little big number

“Levelized cost of energy” (LCOE) measures an energy source’s lifetime costs divided by energy output and is a metric often used for comparing the competitiveness of different energy forms to Read More

Time-lapse gravity

Monitoring strategies for offshore Carbon Capture and Storage (CCS) cannot simply replicate those used in the oil and gas industry, which often rely on 4D seismic methods. Regulations mandate monitoring Read More

Oman – beneath the surface

Much has been written, including in this mag­azine, about the fan­tastic outcrop geology of Oman, the wonderful exposure, the preservation of salt at surface in the arid climate, and the Read More

Chasing zombie wells

“It doesn’t have the dramatic fire and oil shooting out like the bp Macondo well. No, here, in the Permian Basin, wells are spewing fully saturated brine instead”, says Sarah Read More

Digitisation before digitalisation

When a country where some previous exploration efforts took place decides to run another licensing round in an attempt to attract interest from the global exploration community, legacy data quickly Read More

A coup for the country

The Ministry of Energy and Mines in Peru (Minem) recently indicated that the oil industry is ‘being reactivated’. And so far, the signs are indeed pointing in that direction, particularly Read More

The North American helium fairway

As always, news outlets concentrate on the handful of exploration companies trying to prove additional (helium) resources. For instance, Gold Hydrogen announced a record find of 17.5% helium in the Read More

Data is not the new oil

“Deeply misleading”, that’s how Thomas Halsey describes the commonly cited phrase “Data is the new oil”. At least when it comes to data held by the upstream industry. The main Read More

Peat: So hot right now

“The offshore wind sector is still very much a geotechnical exercise”, I was told recently by someone with knowledge on the matter. “But that model is due an update.” Despite Read More

Seeing around OBM

Geochemical analyses focused on characterising oil are frequently challenged by contamination with oil-based muds (OBM). This renders the results either uncertain or in some cases unusable, particularly in solvent extraction Read More

Gold hydrogen – or Gold helium?

On Wednesday 22 May, Gold Hydrogen’s share price reached its highest level so far at 2.09 Australian dollars. A few days later, following the release of an ASX statement on Read More
