the table below shows daily oil production in 4 countries.

The table presents the progress on daily production of oil in 4 countries over a 4 years period, starting from 2000. Overall, while Congo witnessed a downward trend, there were upward trends in other countries. As can be seen, Congo produced the highest amount of oil in the beginning; however it ‘s figure started to fall down over time and reached 204, 000 litres per day in 2004. On the contrary, starting from 205, 000 litres per day, Nigeria’s daily oil manufacture touched its bottom at 190, 000 litres in 2002 then stealy increased to 215, 000 litres per day, taking the first place in the amount of oil generated per day. Turning to Chad and Somalia, a similarity can be seen between those developments. Whereas Somalia boosted its daily oil production from 5000 litres per day to 50000 litres per day, which was 10 times more litres per day, Chad did not begin until 2003 with 8000 litres per day then rocket to 50000 litres per day in 2004.
