Some snakes don’t bite
Everybody is talking about machine learning and big data these days, but what does it mean in reality, and how do geoscientists embrace it in their daily lives? To learn…
Image high-impedance contrasts effortlessly with DUG Elastic MP-FWI Imaging
High impedance contrasts a problem? Never fear. DUG Elastic MP-FWI Imaging is here! DUG Elastic MP-FWI Imaging is a unique approach to seismic processing and imaging which turns the traditional…
Thinking like a geologist in the age of AI
We’re all feeling a tension as geoscientists: Caught between an old way of working and a rapidly changing future dominated by Artificial Intelligence. As the dust starts to settle, another…
How AVO has been and continues to be an essential tool in de-risking the world’s high-impact exploration wells
Henry Pettingill, who is a geologist by training, became the head of the Rose DHI Consortium after having been a member for eighteen years. Geophysicist Rocky Roden has been a…
Uplifting land data with DUG Elastic MP-FWI Imaging
When it comes to processing and imaging land seismic data, DUG Elastic MP-FWI Imaging produces far superior results! Land seismic data, such as the example above, can often exhibit strong…
Crafting a software that is ready for the future
As much as there is a consolidation happening in the large operator landscape and the seismic acquisition space, the same applies to the subsurface software business. “Let’s face it,” says…
Unlocking fractured basement reservoirs
Fractured basement reservoirs, often igneous or metamorphic rocks like granite or gneiss, contrast with conventional sedimentary reservoirs. Without primary porosity, they depend on fracture networks for hydrocarbon storage and flow.…
Coring process step by step
We often talk about core being the only ground-truth data from the subsurface, but how is core cut from a well at kilometres depth? With many geologists being stuck to…
DUG Elastic MP-FWI Imaging: Superior rock properties from field data input!
DUG Elastic MP-FWI Imaging enables simultaneous inversion of reflectivity (3-component, directional, horizontal), P-wave velocity, S-wave velocity, density, P-impedance and S-impedance, providing quantitative interpretation-ready outputs of the highest resolution and amplitude…
Why traffic light play maps are useless
When exploring a new area, it is common for E&P companies to produce traffic light maps, with red areas being the ones where one of the key play elements is…
Seismic data on the workbench
“My goal is to equip explorationists with a toolbox containing all relevant algorithms to efficiently create optimal seismic volumes for interpretation and stratigraphical analysis,” says Anders, who hails from Sweden…
