Introduction to Machine Learning/Data Analytics for Subsurface Engineering and Geoscience Applications - IMLD

The interpretation of rich, heterogeneous and even real-time data has become possible because of recent advances in machine learning and the broader availability of computational power. The oil and gas industry is harnessing the power of this data-driven revolution to create actionable insights from real-time production, drilling, and completions data, SCADA data streams, 3D and 4D seismic, well data such as cores, well-logs, thin-sections and SEM images and even the advent of newer data type such as DTS/DAS measurements.

This 2-day course will introduce participants to the concepts of exploratory data analyses, machine learning workflows and most importantly, data analytics and machine learning use cases for subsurface applications.

There is also an on-demand eLearning version of this course - see details

The course is presented in three modules:

1. Introduction to data-driven workflows including data types, data quality checks and exploratory data analyses
2. Unsupervised learning and clustering with emphasis on the use cases and workflows
3. Supervised learning (including regression and classification) focusing on the use cases and workflows.
