At-bit estimation of rock density from real-time drilling data using deep learning with online calibration
Arnø, Mikkel Leite; Godhavn, John-Morten; Aamo, Ole Morten (Peer reviewed; Journal article, 2021)We present a novel streaming learning approach, utilizing a deep neural network (DNN) to learn from data available during operation to estimate at-bit density using drilling parameters. Since every wellbore is different, ... -
At-bit LWD estimation, lithology classification, and pressure control using machine learning
Arnø, Mikkel Leite (Doctoral theses at NTNU;2021:384, Doctoral thesis, 2021)The petroleum drilling process involves an array of complicated operations necessary to create circular wellbores to allow the exploration and recovery of hydrocarbons. Examples of these are overcoming the resistance, ... -
Classification of Drilled Lithology in Real-Time Using Deep Learning with Online Calibration
Arnø, Mikkel Leite; Godhavn, John-Morten; Aamo, Ole Morten (Peer reviewed; Journal article, 2021)Decision making to optimize the drilling operation is based on a variety of factors, among them real-time interpretation of drilled lithology. Because logging while drilling (LWD) tools are placed some meters above the ... -
Deep Reinforcement Learning Applied to Managed Pressure Drilling
Arnø, Mikkel Leite; Godhavn, John-Morten; Aamo, Ole Morten (Chapter, 2020)During drilling operations, maintaining a desired downhole pressure between pressure margins is crucial to avoid damage to the formation and the well. The process is highly nonlinear, changing with depth, and every section ... -
A divided and prioritized experience replay approach for streaming regression
Arnø, Mikkel Leite; Godhavn, John-Morten; Aamo, Ole Morten (Peer reviewed; Journal article, 2021)In the streaming learning setting, an agent is presented with a data stream on which to learn from in an online fashion. A common problem is catastrophic forgetting of old knowledge due to updates to the model. Mitigating ... -
The Design and Implementation of a Control System for an Autonomous Miniature Drilling Rig
Arnø, Mikkel Leite (Master thesis, 2018)The work presented in this thesis is concerned with the control system of the autonomous miniature drilling rig NTNU has entered and competed with in the international Drillbotics competition. A brief listing of the status ...
