Difference between revisions of "Water bubble point pressure"

Revision as of 05:35, 1 October 2020

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.

-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) <ref name= M1990/>.
