The table below illustrates daily oil production in 4 countries over the course of 5 years, starting from 2000.
Overall, there was a downward trend in the production of Congo, while the manufacture of Nigeria, Chad and Somaila witnessed upward trends over the given period. Another outstanding feature is Congo initially surpassed are the countries in the production; however, it was eventually overtaken by Nigeria.
To begin, in spite of considerable decline in the invention of Nigeria in three years first, that experienced a significant rise to 213.000. The proportion of Chad remained steady, showing no change from 2000 to 2002, then this escalated sharply to 50.000 in 2004. Similarly, Somaila boosted to 50.000 in the manufacture in the end of the period.
By contrast, while the three countries increased in production, the opposite was true in the case of Congo. This figure recorded a dramatic decrease at 50.000 until the end of the period.
