Example source [1]
Input data
- at 3176 psia and 165°F
Estimate the density of the brine at standard conditions (14.7psia & 60°F) and at 3176 psia and 165°F?
Solution
Nomenclature
- = water formation volume factor, res bbl/STB
- = water salinity or solids concentration, mg/l
- = water density at standard conditions, lbm/ft3
