34 – Tight Oil / Shale Oil
What you will learn
- Insights into the many varieties of tight oil plays
- Step-by-step procedures for analysis
- “Computer ready” mathematics
- Answer oriented results, with quality control guided by core assays
This course covers the visual and numerical log analysis methods for evaluating tight oil plays. First we will distinguish between tight oil (in low porosity clean or shaly sands and low porosity carbonates) from true oil shales (course 31) and from so-called “shale oil” plays. Tight oil and shale oil plays may or may not contain mature kerogen, and may therefore contain some adsorbed gas. You will learn the specialized knowledge required to address the kerogen and shale corrections required in this unconventional environment. Radioactive sands and low resistivity sands are also covered in detail. Examples specific to this environment are provided.
