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…
A Generative-AI Modeling Framework for Explainable Decision Support in Complex Geosteering Scenarios
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…
High-Precision Geosteering via Reinforcement Learning and Particle Filters
Ressi Bonti Muhammad, Apoorv Srivastava, Sergey Alyaev +2
Geosteering, a key component of drilling operations, traditionally involves manual interpretation of various data sources such as well-log data. This introduces subjective biases a…
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…
3D induction log modelling with integral equation method and domain decomposition preconditioning
Durra Handri Saputera, Morten Jakobsen, Koen W. A. van Dongen +3
The deployment of electromagnetic (EM) induction tools while drilling is one of the standard routines for assisting the geosteering decision-making process. The conductivity distri…
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…
