Types of Shale - Background Thermogenic: a conventional HC source without migration pathways Primary biogenic: shallow depth in a biogenic kitchen with limited migration Secondary biogenic: meteoric waters & anaerobic bacteria generate…
Toolebuc Geology Organic rich shale found across the basin (up to 20% TOC, average 9.5%) Depth range surface 900m across EXE permits Over 25,000km2 of shale, up to 40m thick Uncertain thermal maturity and therefore uncertain resource…
