Paper Number: SPE-211407-MS
... 0.490 to 0.510 psig/ft for the formation water ranges from 1.15 to 1.18 specific gravity, depends on formation water salinity. Oil with an SG of 0.82 to 0.89 has a fluid pressure gradient of 0.355 to 0.385 psig/ft (depending on the API oil). The formation water salinity, and specific gravity from...
