The table illustrates the daily oil production of four countries – Nigeria, Chad, Congo and Somalia – between 2001 and 2004, measured in barrels per day.
Overall, Congo produced the highest amount of oil at the beginning of the period, although its production gradually declined over time. In contrast, Nigeria showed a slight increase, while Chad and Somalia experienced significant growth, especially towards the end of the period.
In 2001, Congo was the leading producer with 275,000 barrels per day, followed by Nigeria at 205,000 barrels. However, Congo’s output decreased steadily to 234,000 in 2002, 212,000 in 2003 and finally 203,000 in 2004. Meanwhile, Nigeria’s production fluctuated slightly, falling to 201,000 in 2002 before rising to 210,000 in 2003 and reaching 213,000 barrels in 2004.
By contrast, Chad had no oil production in 2001 and 2002, but it started producing 8,000 barrels in 2003 and increased sharply to 50,000 in 2004. Similarly, Somalia’s production rose consistently from 5,000 in 2001 to 50,000 barrels per day in 2004.
