(10%) The Aqua Vitae No. 1 well in the Rara Avis Field has the production history shown in the graph below. The separator gas is metered and has an operating pressure of 110 psia and an operating temperature of 90 o F. The specific gravity of the separator gas is 0.8 and the stock-tank oil gravity is 30 o API. Estimate the bubble point pressure and the solution GOR at the bubble point.
