The table shows the average daily oil production in 4 different countries from 2000 to 2004
Overall, Congo and Nigeria were the first and second leading oil producers throughout the period, respectively. In contrast, Chad and Somalia produce daily oil in smallest quantities at all times of the period. Additionally, Congo was the only country that experienced a decline compared to all other countries
In 2000, Congo reported daily oil production of 275,000 barrels per day, and Nigeria followed closely with 205,000 barrels per day in the first year. After that year, Congo experienced a continuous decline from the following year to the end of the period, with the figure decreasing by 72,000 barrels compared to the first year. In contrast, Nigeria had a relatively decrease to 190,000 barrels in 2002, but increased immediately afterward to 213,000 barrels by the end of the period
Regarding Chad and Somalia. During the first three years, Somalia produced only an average of 5,000 barrels a day, and Chad was in a non-productive addition. After that, Chad started to manufacture its first barrels of oil and achieved an average of 8,000 barrels per day, and Chad’s production increased significantly to 50,000 barrels per day by the end. As Chad, Somalia also increased, and the production in Somalia also increased equally compared to that in Chad at the end of the period
