WebOct 22, 2024 · Based on API gravity crude oil is classified as light component oil (API ˃ 31.1°, sg ˂ 870 kg/m 3 ), medium quality oil (22.3° ˂ API ˂ 31.1°, sg 870–920 kg/m 3 ), heavy crude oil (10° ˂ API ˂ 22.3°, sg 920–1000 kg/m 3 ), and the extra-heavy crude (black) oil (API ˂ 10°, sg ˃ 1000 kg/m 3 ). When oil is produced to surface temperature and pressure it is usual for some natural gas to come out of solution.
