Bubble Point prediction from BHP

[ahmedj9579]

how are you doing all?
please can some one clarify to me this point: how can we estimate Bubble point Pressure from BHP gradient survey?
many thanks!

please, recommendations!

I'll get some discussion started by saying you cant do that - you cannot predict Pb from a BHP measurement.

only if you have gas cap than at GOC oil is at Pb (Psat)

please i-anuar, can we explain again. i didn't get your point!!!

oil is saturated at the contact with gas, i.e. at the saturation/bubble point pressure.
oil couldn't dissolve all the gas, for varios reasons, pressure too low, temperature too high etc and therefore it is saturated. saturation pressure is pressure at the GOC...
