Question #63220

In a gas reservoir, the gas is flowing out at a rate of 2500 scf per hour. The pressure of

the reservoir is constant at 1575 psia. The residual gas saturation is assumed to be 23%

and the gas volume factor at the reservoir pressure is 55.23 scf/cft and at surface

condition it is 176.8 scf/cft. Reservoir volume is3.2 oc.ft. Porosity is 22% connote

water 18.6%.

Question :

1) Calculate volume of the gas in the reservoir?

2) Calculate volume of the gas retained in the reservoir?

3) Find the time taken for recovering 55% of the reservoir gas?

4) Find Net available gas?
