I'm Andy McDonald, a petrophysicist / data scientist within the oil and gas industry based in Aberdeen, Scotland
I have over 15 years experience in petrophysics, log analysis and geoscience. In recent years I have become interested in how Python development and Machine Learning can be applied to the challenges and problems we face when carrying out petrophysical analysis.
When I am not doing my day job I can be found out with the camera photographing nature, catching up on the latest SpaceX launches or learning about productivity and Notion.
