The chart illustrates how much oil was produced daily in 4 different countries, namely Nigeria, Chad, Congo and Somalia in the course of 4 years, starting in 2000.
Overall, there were upward trends in the daily production of oil in Nigeria, Chad and Somalia, with the exception of Congo witnessing a considerable decline between 2000 and 2004. Despite this, Congo consistently registered the highest figures among the countries examined before being surpassed by Nigeria in 2004.

Meanwhile, 5.000 barrels of oil were produced in the year 2000 in Somalia, followed by a moderate rise to 50.000bpd in the end of the period.
