31 – Immature Oil Shale
What you will learn
- Specific quantitative analysis sequence for oil shales with immature kerogen
- “Computer ready” mathematics
- Answer oriented results, with quality control guided by core assays
This course covers the numerical log analysis methods for evaluating oil shales with immature kerogen, such as those in the Green River Basin in Utah and Colorado, Immature oil shales must be distinguished from tight oil plays with mature kerogen, sometimes called shale oil or oil shale plays (Lecture 34). You will learn the specialized knowledge required to calculate oil yield in US gallons per ton of rock and how to calibrate this result to Fischer method core assay data. Examples specific to this environment are provided.
- Crain’s Integrated Petrophysics, Lectures 1 to 11 or equivalent background.
- Basic understanding of geology and logging tool response.
- Oil Shale Basics
- Classifying Oil Shales
