Functions

brine(temperature, pressure, salinity)

brine_density(temperature, pressure, salinity)

density of sodium chloride solutions, equation 27 in Batzle & Wang [1]. :param salinity: Salinity of solution as weight fraction (ppm/1000000) of sodium chloride. :param pressure: Pressure (MPa) of oil :param temperature: Temperature (celsius) of oil. :return: density of solution in g/cc.

brine_primary_velocity(temperature, ...)

Primary wave velocity of sodium chloride solutions, equation 29 in Batzle & Wang [1].
