30 – Gas Shale
What you will learn
- Provides insights and specific quantitative calculation sequence for shales gas analysis.
- Provides “computer ready” mathematics.
- Answer oriented results, with quality control guided by core assays.
This course covers visual and numerical log analysis methods for evaluating shale gas reservoirs with mature kerogen. We distinguish shale gas from shaly sands with gas and laminated shaly sands with gas by the presence of adsorbed gas associated with the kerogen in a shale gas zone. You will learn the specialized knowledge required to calculate free gas and adsorbed gas volumes and how to calibrate this result to core analysis, Rock Eval (TOC), and XRD mineralogy data. Examples specific to this environment are provided.
