The table below shows the percentages of different fractions obtained from crude oil sourced from three different oil reserves: Brent Crude, WTI Crude, and Maya Heavy.
| Fraction | Percentage of fraction in Brent Crude (%) | Percentage of fraction in WTI Crude (%) | Percentage of fraction in Maya Heavy (%) |
|---|---|---|---|
| Refinery Gases | 4 | 6 | 2 |
| Gasoline | 22 | 28 | 10 |
| Kerosene | 15 | 14 | 8 |
| Diesel | 24 | 22 | 15 |
| Fuel Oil | 25 | 20 | 35 |
| Bitumen | 10 | 10 | 30 |
A sample of crude oil from the Brent Crude reserve has a mass of 180 kg.
