Strategic Investment Decision Making for Value Creation in Energy Transition: A Reinforcement Learning Approach
Yasaman Cheraghi, Reidar B. Bratvold, Aojie Hong +2
The global challenge of climate change has driven significant steps to reduce CO2 emissions, guided by international agreements like the Paris Agreement of 2015. Acting too slowly…
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…
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…
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…
An interactive sequential-decision benchmark from geosteering
Sergey Alyaev, Reidar Brumer Bratvold, Sofija Ivanova +2
Geosteering workflows are increasingly based on the quantification of subsurface uncertainties during real-time operations. As a consequence operational decision making is becoming…
Man vs machine: an experimental study of geosteering decision skills
Sergey Alyaev, Reidar Brumer Bratvold, Sofija Ivanova +2
With the steady growth of the amount of real-time data while drilling, operational decision-making is becoming both better informed and more complex. Therefore, as no human brain h…
A Decision Support System for Multi-target Geosteering
Sergey Alyaev, Erich Suter, Reidar Bratvold +2
Geosteering is a sequential decision process under uncertainty. The goal of geosteering is to maximize the expected value of the well, which should be defined by an objective value…
