Better Automatic Interpretation of Cement Evaluation Logs through Feature Engineering
(Chapter, 2021)We build systems to automatically interpret cement evaluation logs using supervised machine learning (ML). Such systems can provide instant rough interpretations that may then be used as a basis for human interpretation. ... -
Better Automatic Interpretation of Cement Evaluation Logs through Feature Engineering
(Journal article; Peer reviewed, 2021)We investigate systems to automatically interpret cement evaluation logs using supervised machine learning (ML). Such systems can provide instant rough interpretations that may then be used as a basis for human interpretation. ... -
Data Driven Filtering of Bowel Sounds Using Multivariate Empirical Mode Decomposition
(Journal article; Peer reviewed, 2019)Background The analysis of abdominal sounds can help to diagnose gastro-intestinal diseases. Sounds originating from the stomach and the intestine, the so-called bowel sounds, occur in various forms. They are described ... -
Getting started with acoustic well log data using the dlisio Python library on the Volve Data Village dataset
(Chapter, 2020)Three issues have long impeded academic research and teaching on well logging. First, real measured data has been hard to come by. This has now been alleviated by Equinor's 2018 release of the Volve Data Village dataset. ... -
Modelling acoustic radiation from vibrating surfaces around coincidence: Radiation into fluids
(Peer reviewed; Journal article, 2023)It is well-known that vibrating surfaces generate sound waves in adjacent fluids. According to the classical radiation model, the nature of these waves depends on whether the vibration’s phase speed cv is above (supersonic) ...
