Probabilistic forecasting for geosteering in fluvial successions using a generative adversarial network
Sergey Alyaev, Jan Tveranger, Kristian Fossum +1
Quantitative workflows utilizing real-time data to constrain ahead-of-bit uncertainty have the potential to improve geosteering significantly. Fast updates based on real-time data…
Probabilistic model-error assessment of deep learning proxies: an application to real-time inversion of borehole electromagnetic measurements
Muzammil Hussain Rammay, Sergey Alyaev, Ahmed H Elsheikh
The advent of fast sensing technologies allows for real-time model updates in many applications where the model parameters are uncertain. Bayesian algorithms, such as ensemble smoo…
Numerical studies of long-term wettability alteration effects in CO storage applications
David Landa-Marbán, Kundan Kumar, Sarah Eileen Gasda +2
The wettability of the rock surface in porous media has an effect on the constitutive saturation functions that govern capillary pressure and relative permeability. The term wettab…
Practical approaches to study microbially induced calcite precipitation at the field scale
David Landa-Marbán, Svenn Tveit, Kundan Kumar +1
Microbially induced calcite precipitation (MICP) is a new and sustainable technology which utilizes biochemical processes to create barriers by calcium carbonate cementation; there…
Modeling of relative permeabilities including dynamic wettability transition zones
Abay M. Kassa, Sarah E. Gasda, K. Kumar +1
Wettability is a pore-scale property that impacts the relative movement and distribution of fluids in a porous medium. There are reservoir fluids that provoke the surface within po…
