The formation water (brine) isothermal viscosity correlation is published by McCain in 1991^[1].

Water viscosity

\mu_{w1} = AT^{-B}

^[1]

where

A = 109.574 - 8.40564 C_W + 0.313314 C_W^2 + 0.00872213 C_W^3

^[1]

B = -1.12166 + 2.63951(10^{-2}) C_W - 6.79461(10^{-4}) C_W^2 - 5.47119(10^{-5}) C_W^3 + 1.55586(10^{-6}) C_W^4

^[1]

\mu_{w} = \mu_{w1} (0.9994 + 4.0295(10^{-5})\ P + 3.1062(10^{-9})\ P^2)

^[1]

C_{mg/l} = 74289.3

SG_w = 1.0476

Calculate water viscosity at 3176 psia and 165°F?

C_W = 74289.3 / 1.0476 / 10000 = 7.1%

A=68.83262779

B=0.984227021

\mu_{w1} = 0.45

\mu_w = \mu_{w1} 1.1587 = 0.52 cP

C_{mg/l}

= pressure correction, res bbl/STB

C_W

= water salinity or weight percent solids, %

P

= pressure, psia

T

= Temperature, °F

\mu_w

= water viscosity, cP
