- •
The Es3 Formation saline mudstones, from which shale oil is being produced, are dominated by type II kerogen.
- •
The Es3 Formation saline mudstones are in the early mature to fully mature stage of oil generation.
- •
Tectonic, bedding plane, diagenetic shrinkage, and over-pressured fractures are well developed in saline mudstones.
- •
Mineral interparticle, mineral intraparticle and organic matter pores are well developed in saline mudstones.
- •
Micro-fractures and dissolution pores appear to be the main controls on the shale oil accumulation.
