PETE 2032 Homework Solutions – Chapter 5 5.6 A field in north Louisiana discovered in 1953 and developed by 1956 had an initial producing gas-oil ratio of 2000 scf/STB. The stock-tank liquid was “medium orange” and had a gravity of 51.2 o API. Classify this reservoir fluid. Volatile Oi GOR = 2000 scf/STB o API = > 40 Color: orange 5.7 During the producing history of the field in Exercise 5-6 the stock-tank liquid gravity steadily increased to 63 o API, and the producing gas-oil ratio increased to a maximum of 29,000 scf/STB. Does this information confirm your classification? Why or why not? Yes, volatile oil. Increase in o API from 51.2 to 63. 5.8 Laboratory analysis of a sample from the reservoir of Exercise 5-6 gave the following composition. Component Composition mole fraction CO 2 0.0218 N 2 0.0167 C 1 0.6051 C 2 0.0752 C 3 0.0474 C 4 0.0412 C 5 0.0297 C 6 0.0138 C 7+ 0.1491 1.0000 Properties of heptanes plus Specific Gravity Molecular weight 0.799 181 lb/lb-mole The formation volume factor was about 2.6 res bbl/STB.
