Experiments were made on a bottom-hole sample of the reservoir liquid taken from the lasaale oil field to determine the solution gas and formation volume factor as a function of pressure. The initial bootom hole pressure of the reservoir was 3700 psia, and bottom-hole temperature was 160°F; so all measurements in the laboratory were made at 160°F. The following data, converted practical units were obtained from the measurements: Solution gas SCF/STB at 14.7 psia and 60°F Pressure Formation Volume factor psia Bbl/STB 3700 567 1.310 3200 567 1.317 2800 567 1.325 2500 567 1.333 2400 554 1.310 1800 436 1.263 1200 337 1.210 600 223 1.140 200 143 1.070 Based on the above data a. If the reservoir contains 280 MM reservoir barrels of oil initially, what is the initial number of STB in place? b. If initial water saturation is 0.18 what is the initial volume of dissolved gas in an acre-ft of the reservoir? If the reservoir pressures drops to 1800 psia how much reservoir volume would a 1000 STB oil occupy with its dissolved gas ? c.
