Water bubble point pressure
The bubble point of a gas-saturated formation water (brine) is equal to the bubble point pressure of coexisting oil [1].
The two are equal because of thermodynamic equilibrium between the brine and the oil.
Math and Physics
Conversions
Often, parts per million and milligrams per liter are used interchangeably. This is correct only if the density of the brine at standard conditions can be assumed to be 1 g/cc ( 1000 kg/m3, SG_w=1, 62.428 lbm/ft3) [1].
Nomenclature
