Need help with Quantification and evaluation of crude oil reserves!

[Gitta]

Thanks vinomarky,

You reply was very helpful. However I still need help. I have been furnished with the following information;

1. Petrel model
2. Density
3. Volume factor
4. Viscosity
5. Surface vsicosity
6. GOR
7. The relative density of gas
8. Surface density
9. Formation water viscosity
10. Formation volume factor of water
11. Oil compressibility
12. Formation water compressibility

I am supposed to use the above given information plus Petrel to estimate the crude oil reserves. If anyone has an idea about how I can go about the process please share. You can either share here or send to my email at gilo_38k@yahoo.com.

Thanks

Gilbert

With the Petrel model (and I'm assuming hydrocarbon column height info or pre-populated hydrocarbon saturations) then calculating the hydrocarbon in place is a matter of using the Petrel Volume Calculation process (under Utilities), and dropping in the NTG (if present), porosity, oil and gas saturations and it will spit out HC in place. To work out reserves is another matter altogether as you need to come up with the magical recovery factor, and if you don't have any idea as what to use then (sorry to be blunt) you should not have been asked to calculate the reserves
