Bo

[hebatt]

do you have any composition data ?
you can use PVT simulation software if you have composition data, it's less then 5 minutes if you have the data.

or if you don't have it,
see in Mccain's book whether the 25 API refer to black oil or volatile oil properties (it's black oil in Mccain),
and see the range of Bo in the black oil provided by the book.

now you have the range of Bo, thus you can use that range for sensitivity study,
if you are utilising Bo for in place calculation, then use the maximum value provided in the range for pessimistic calculation. In Diversion, use the Bo minimum value for the optimistic calculation.

hope this one will help you.
