d. If the reservoir fluid is the same as mixture 5 on Fig. 2-37, it should be classified as Volatile Oil. e. If the reservoir fluid is the same as mixture 6 on Fig. 2-37, it should be classified as Black Oil. Problem 5-2 Case 1 At a location 5.8 miles south-southeast of Kurten, International Drilling System has finaled a new producer in Brazos County’s Buda Field. The well is designed as the No. 1 Cargill/Chase, flowed ten barrels of oil per day, along with 50,000 CF casinghead gas on an 18/64-in. choke. Location is in an 814-acre lease in the B.F. Stroud Survey. Bottomed at 10,059 feet, the well will produce from perforations in the Buda Formation, 9,799 to 10,042 feet into the wellbore. Answer to Case 1: GOR = STB scf d stb d scf / 000 , 5 / 10 / 000 , 50 = This GOR indicates that we have a Retrograde Gas . Case 2 Patterson Petroleum of Houston filed first production figures on a new oil well in the Giddings Field, Washington County. The No. 1 Fischer showed potential to flow 350
