Is it possible to differentiate between meandering and braided river deposits using gamma-ray logs?

May 5, 2023

For most people working in subsurface teams, discussions related to the interpretation of depositional facies on the basis of well logs are part of the daily routine. The more geologists…

Pumped geothermal power projects – a global overview

Elliot Yearsley

April 26, 2023

Pumped-well geothermal projects utilise the moderate temperature range of geothermal fluids between 100-190 C. Below this temperature, geothermal fluids are generally used for direct heating and above this the fluids…

Seismic acquisitions focus on mature hydrocarbon provinces

Henk Kombrink

April 20, 2023

As always, conferences are great places to gauge the state of play of the industry. Yesterday, I talked to several people with good insight into the seismic acquisition business at…

Swimming in subsurface data – on YouTube

Henk Kombrink

April 19, 2023

A new way of providing subsurface intelligence is the use of videos compiled by geoscientists. Sharing content in this way can be rewarding but daunting at the same time. That…

Well logs and facies interpretation – Who gets it right?

For most people working in subsurface teams, discussions related to the interpretation of depositional facies on the basis of well logs are part of the daily routine. The more geologists…

Sequences, sea-level curves and predictive power: Assuming simplicity does not correctly predict complexity

Peter Burgess - School of Environmental Science, University of Liverpool

April 2, 2023

Pre-drill predictions of basin-fill strata, in the absence of substantial supporting data, have been a key objective of seismic and sequence stratigraphic methods including global sea-level curves since the original…

In the UK, it is not that long ago that people had to go to the Department of Energy and Climate Change – which is now the North Sea Transition…

More wells should be drilled with water-based mud

Henk Kombrink

March 17, 2023

“All cuttings brought to surface need to be shipped ashore when they are contaminated with oil-based mud (OBM)”, says Anita Hansen in a recent conversation. Anita has decades’ worth of…

A new global sea-level curve

Douwe van der Meer and Kent Wilkinson, CNOOC

March 13, 2023

Traditional long-term eustatic sea-level reconstructions suffer from uncertainty in stratigraphic interpretations of the rock record, which leads to ambiguity. Sea-level reconstructions from plate tectonic modelling are limited in use due…

The production chemistry challenges of geothermal energy

Henk Kombrink

February 23, 2023

“The geothermal industry requires a much tighter control on scale formation than the oil and gas industry”, said Peter Wilkie from Roemex in a talk delivered during SPE’s online Geothermal…

Cutting data – please handle with care!

Henk Kombrink

February 22, 2023

“It’s not precise at all, so please handle with care”, is one of the first things Anita Hansen tells me when we meet on Teams. We spoke about working with…

“I got kind of bored and underutilised sitting on the sidelines “refreshing” job pages”

Henk Kombrink

February 10, 2023

“I decided to put my work out there and keep myself active, rather than just reposting work from others”, Jamie Vinnels wrote in an email. Jamie has been compiling subsurface…
