Variation of Contact Angles in Brine/CO₂/Mica System considering Short-Term Geological CO₂ Sequestration Condition

Table 1

The parameters used to calculate capillary pressure in different effective stress or depths.

Pressure	Pore diameter (nm)	Interfacial tension (mN/m)
		Salinity (0 M)	Salinity (1 M)	Salinity (3 M)
3	95	54.1	55.9	58.6
5	60	38.1	41.9	47.8
7	44	30.9	35.3	40.8
10	32	24.2	29.1	33.2
13	25	-	25.2	28.7

Note. The brine in the present work was made of water and NaCl. However, the brine used in the study by Bachu and Bennion [52] was made of several types of ions.
