Calculates Brine properties from modified Spivey Correlation per McCain Petroleum Reservoir Fluid Properties pg 160. Includes effect of user specified salt concentration and degree of methane saturation.
Returns tuple of (Bw (rb/stb), Density (sg), viscosity (cP), Compressibility (1/psi), Rw GOR (scf/stb))
brine_props(p, degf, wt, ch4_sat) -> tuple| Parameter | Type | Description |
|---|---|---|
| p | float | Pressure (psia) |
| degf | float | Temperature (deg F) |
| wt | float | Salt weight% in the brine (0-100) |
| ch4_sat | float | Degree of methane saturation (0 - 1). 0 = No Methane, 1 = 100% Methane saturated |
Examples:
>>> from pyrestoolbox import pyrestoolbox as rtb
>>> bw, lsg, visw, cw, rsw = rtb.brine_props(p=160, degf=135, wt=1.5, ch4_sat=1.0)
>>> print('Bw:', bw)
>>> print('SGw:', lsg)
>>> print('Visw:', visw)
>>> print('Cw:', cw)
>>> print('Rsw:', rsw)
