On page 19, equation (2), letter ‘ρ’ represents live oil density. It was incorrectly shown as letter ‘r’ on page 20.
where ρ is live oil density, ρst is dead oil density and γg is gas density (all in g/cm3). This equation was rearranged so that live oil density could be predicted from the remaining parameters:
On page 21, in the formula for live oil viscosity μ the live oil density in the exponent should be ρ squared (ρ2 not ρ2):
