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

A, B

= coefficients

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

\mu_{w1}

= water viscosity at 1 atm, cP
