Prediction of gas cap performance using fetkovich model in Kharir Field

Abstract EN

Correlation Fetkovich is Estimate reservoir properties and compare it with that reported from the test for each well, determine ultimate gas cap recovery, determine the remaining reserves.

In our paper we use an Excel sheet was developed based on the method used to match the production data and predicting the future production of Kharir-1 and Kharir-2.

The best decline curve fit for the history of Kharir-1 is b = 0.00 and Kharir-2 is b= 0.2.

as well as all estimated reservoir properties are in good fit with that reported from the test for each well.

Ultimate gas recovery (EUR) for Kharir-2 and Kharir-1 respectively are 1968036 Mscf and 730606 Mscf which means 34.29% and 45.28% recovered from the initial gas in place.

Also, the remaining reserve is 128136 Mscf of the initial gas in place in Kharir-2 whereas Kharir-1 is 8280 Mscf.
