A decision support system for multi-target geosteering
Alyaev, Sergey; Suter, Erich; Bratvold, Reidar Brumer; Hong, Aojie; Luo, Xiaodong; Fossum, Kristian (Journal article; Peer reviewed, 2019-12)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-function for each operation. In this paper ... -
An interactive sequential-decision benchmark from geosteering
Alyaev, Sergey; Ivanova, Sofija; Holsaeter, Andrew Martin; Bratvold, Reidar Brumer; Bendiksen, Morten (Peer reviewed; Journal article, 2021)During drilling, to maximize future expected production of hydrocarbon resources, the experts commonly adjust the trajectory (geosteer) in response to new insights obtained through real-time measurements. Geosteering ... -
Probabilistic model-error assessment of deep learning proxies: an application to real-time inversion of borehole electromagnetic measurements
Rammay, Muzammil Hussain; Alyaev, Sergey; Elsheikh, Ahmed (Peer reviewed; Journal article, 2022)The advent of fast sensing technologies allow for real-time model updates in many applications where the model parameters are uncertain. Once the observations are collected, Bayesian algorithms offer a pathway for real-time ...
