Benchmarking CO Storage Simulations: Results from the 11th Society of Petroleum Engineers Comparative Solution Project
Jan M. Nordbotten, Martin A. Fernø, Bernd Flemisch +40
The 11th Society of Petroleum Engineers Comparative Solution Project (shortened SPE11 herein) benchmarked simulation tools for geological carbon dioxide (CO) storage. A total o…
Strategic Geosteering Workflow with Uncertainty Quantification and Deep Learning: A Case Study on the Goliat Field
Muzammil Hussain Rammay, Sergey Alyaev, David Selvåg Larsen +2
The real-time interpretation of the logging-while-drilling data allows us to estimate the positions and properties of the geological layers in an anisotropic subsurface environment…
Verification of a real-time ensemble-based method for updating earth model based on GAN
Kristian Fossum, Sergey Alyaev, Jan Tveranger +1
The complexity of geomodelling workflows is a limiting factor for quantifying and updating uncertainty in real-time during drilling. We propose Generative Adversarial Networks (GAN…
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…
Direct multi-modal inversion of geophysical logs using deep learning
Sergey Alyaev, Ahmed H. Elsheikh
Geosteering of wells requires fast interpretation of geophysical logs, which is a non-unique inverse problem. Current work presents a proof-of-concept approach to multi-modal proba…
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…
Field-scale impacts of long-term wettability alteration in geological CO storage
Abay Kassa, Sarah Eileen Gasda, David Landa-Marbán +2
Constitutive functions that govern macroscale capillary pressure and relative permeability are central in constraining both storage efficiency and sealing properties of CO stor…
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…
