Fluid properties at 45 degree Celsius and atmospheric pressure.

	Density (g/cc)	Viscosity (cp)	Viscosity ratio, /	Density ratio, /	IFT, (dynes/cm)
Brine	1.0204	0.5653	0.0329	0.1019	62
Nitrogen	0.104	0.0186

and denote the viscosity of gas and water, while and denote the density of gas and water. IFT denotes interfacial tension between gas and water and is denoted by .
