The provided table illustrates how many oil barrels were produced per day in Nigeria, Chad, Congo, and Somalia between 2000 and 2004. Overall, Congo was the largest oil producer at the beginning of the period, but its output declined steadily throughout the five years. Nigeria, by contrast, experienced slight fluctuations before becoming the leading producer by 2004, while both Chad and Somalia recorded substantial growth from very low initial levels. Regarding two major oil production countries, Congo underwent a continuous drop, falling from 275,000 barrels per day in 2000 to 213,000 in 2004. In contrast, Nigeria's production fluctuated steadily, decreasing from 205,000 at the beginning to 190,000 barrels per day by 2002 before recovering to 213,000 at the end of the period, thereby overtaking Congo as the greatest producer. Turning to the remaining countries, where the oil output was fewer by far than two major countries throughout the period, they witnessed a significant increase. Somali recorded steady growth from 5,000 barrels per day in 2000 to 50,000 in 2004. Meanwhile, Chad produced no oil during the first three years before rose to 8,000 in 2003 and then skyrocketed to 50,000 barrels per day in the final year. Consequently, both countries reached the same production level in 2004.
