Decision-Driven Geosteering Under Uncertainty: A Unified Framework for Sequential Decision Optimization
Hibat Errahmen Djecta, Sergey Alyaev, Kristian Fossum +3
Geosteering requires navigating a well trajectory through an unknown geological configuration, while sequentially updating decisions based on indirect measurements acquired during…
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…
DISTINGUISH Workflow: A New Paradigm of Dynamic Well Placement Using Generative Machine Learning
Sergey Alyaev, Kristian Fossum, Hibat Errahmen Djecta +2
The real-time process of directional changes while drilling, known as geosteering, is crucial for hydrocarbon extraction and emerging directional drilling applications such as geot…
Optimal Sequential Decision-Making in Geosteering: A Reinforcement Learning Approach
Ressi Bonti Muhammad, Sergey Alyaev, Reidar Brumer Bratvold
Trajectory adjustment decisions throughout the drilling process, called geosteering, affect subsequent choices and information gathering, thus resulting in a coupled sequential dec…
