Gas sorption screening
This is done using thermovaporisation-gas chromatography (Tvap).
The amount and composition of sorbed gas within source rocks quickly and inexpensively, thereby providing a practical tool for the rapid identification of ‘‘sweet spots” or heterogeneities within vertical profiles.
Samples (1g rock)
High resolution sampling profiles through shales.
- S2-normalised Tvap gas yields correlate with Langmuir amounts (nL)
- Tvap is an effective screening tool for defining the basic sorption characteristics of source rocks or gas shales.
- Adsorptive property profiling is possible for large data sets, enabling optimized sampling for standard Langmuir parameter determinations using classical methods.
