The well is a shut-in-gas well that has a SISP of 1100 psig and a bottomhole pressure of 1760 psia. The well is located on the Gulf Coast. It has a bottomhole temperature of 172F and the produced gas is 39.5 lb/lb mol. The perforations of the producing well are at the GOG. The top of the gas formation is at a depth of 3900\', the thickness of the oil formation is exactly one half of the thickness of the gas formation. The oil has an API three times the API of water. The pressure at the owe is closest to... A) 3015 psia B) 2515 psia C) 2015 psia D) 1985 psia E) 1915 psia F) 1815 psia G) 1600 psia H) 1400 psia

Solution

The Correct option with the given Data is Closest to (C) 2015 psia

Temperature is 172F

SISP is 1100psig

Bottomhole pressure 1760 psia

Volume Produced 39.5 ib/mol

Depth 3900\'

Thickness of oil is ½ of Oil

Z= Actual Volume of Gas at specified T and p/ Ideal Volume of Gas at same T and P

P= (1100+1760)*172/39.5*3900

P= 4919200/154050

P=3114.25

Pressure at The OWC will be (P initial - P final)

i.e

(3114.25-1100)= 2014.25
