A well has just been completed in a newly-discovered black-oil reservoir. Reservoir pressure appears to be above the bubble-point pressure of the oil. Measured at reservoir conditions, 86,3 barrels per day enter the wellbore. The oil is processed through a separator into a stock tank. The stock tank accumulates 57.9 STBs of 44.2API oil each day. The separator produces 43,150SCF/d of 0.724 gravity gas, and the stock tank vents 7240SCF/d of 1.332 gravity gas. a) What is the formation volume factor of the oil? b) What is the solution gas-oil ratio? c) Which of the previous answers applies at the bubble point
