The table below shows the percentage composition by mass of various hydrocarbon fractions obtained from fractional distillation of crude oil samples extracted from three different deep-sea reserves.
| Hydrocarbon Fraction | Percentage in Zeta Reserve (%) | Percentage in Sigma Reserve (%) | Percentage in Omega Reserve (%) |
|---|---|---|---|
| refinery gases | 3 | 5 | 7 |
| gasoline (petrol) | 14 | 10 | 18 |
| kerosene | 18 | 15 | 24 |
| diesel | 21 | 28 | 13 |
| fuel oil | 29 | 30 | 25 |
| bitumen | 15 | 12 | 13 |
State which oil reserve contains the greatest combined percentage of gasoline (petrol) and kerosene.
