A new thread on Reserves

[aquil]

Dear all
presently I want to know if Volume in Place are calculated by praobabilitic method, then is there any point in again calculating the reserves with attached probabilities?

regards

[cappy]

You did not specify, if the volume in place is a speculated estimate, if it is, that is if the well is yet to produce from the reservoir, then you use probabilistic approacch to calculate. Hence your best bet is the P50 estimate.

This paper nicely shows how to do this

Dear Shakespare, dipak-m and cappy
Thanks, for the reply.
Additinally I have one more question. When reserves are calculated based on historical data like decline curve and based on production analysis data like WOR VS CUM PRODUCTION. It is my understanding that reserves based on these data/method should be categorised as P90. But I have seen cases where this resrves have been categorised as P50 specilly in cases where some investment decision was wanted. Please give your views. reservoirs have already produced more than 10 % of originally stipulated P50 Oil in Place.
