Porosity-Permeability Cross-Plot of the Jiamuhe Formation in the Northwest Margin of the Shawan Sag. The classification and distribution of porosity and permeability data are as follows. Type I porosity ranges from 10 − 20% with permeability ranges from (0.1–10) mD, It exhibits medium porosity, low to ultra-low permeability, and located in the Well CP21 area. Type II is porosity ranges from 5 − 14% with permeability ranges from (0.5–50) mD. It exhibits low porosity, extra to low permeability, and located in the Well ZJ 5 area. Type III is porosity ranges from 10 − 18% with permeability ranges from (1–500) mD. It exhibits extra-low porosity, medium-high to extra-low permeability, and located in the Well ZJ 6 area. Type IV is porosity ranges from 4 − 12%, permeability ranges from (0.01–1) mD. It exhibits ultra-low porosity, extra to ultra-low permeability, and located in the Well CP 004 area.
