This is my first discussion on the forum so please forgive me any faux pas but I have something really exciting to share! At work I had some free time and Azure credits so I decided to give their ML lab a whirl. I took a very broad and difficult question, although one that should have had a finite answer, and used some SCADA data to train a model that would be able to predict unplanned downtime in a well far enough ahead as to be able to send out an engineer to apply preventative maintenance. Common idea, I felt, and enough data to work something out. I won't bore you with the details (unless you ask, of course!) but something astonishing and totally unexpected came out of the analysis.
