The gus was bled off and found to occupy a volume of 0. 145 sof. The volume of oil was Recorded as 303 cc. The pressure was Reduced to 14.7 psic and the temperature to 6OF while 058 sof of gas was evolved leaving 230 ce a#of oil with a garity of 42 API . calculate : () gus compressibility factor at 2000 paid b) Gas solubility at 2000 psiu.Ex= 8) Given the following gues composition : ( table ) if Reservoir P & T ane 2500 psia and 1750 F, calculute: a) Gus density by accounting for the presence of Non .
