The bar graph demonstrates the estimated amount of oil, in millions of barrels, produced daily by six Gulf nations across two decades, commencing in 1990.
Overall, these six countries recorded an upward trend in the oil production capacity over the surveyed time frame. Noticeably, Saudi Arabia was consistently the primary oil producer throughout the given period, while Qatar’s production level was the lowest.
Regarding countries with moderate petroleum production levels, Iran started the period with 3.2, after which it increased gradually to 4.4 in the last year. Similarly, Iraq showcased an increment in the production capacity of this fuel, initiating with 2.2 before ascending to 4.0 by 2010, whereas UAE manifested a stability of 2.5 in the first ten years of the period and later exhibited a augmentation to 3.8 by 2010. Moreover, Kuwait’s capacity rose from 1.8 in 1990 to 3.5 in 2010.
Concerning the remaining nations, Saudi Arabia maintained its lead for all four years listed at 8.5, 9.5, 12.5, and 14.5, respectively. In contrast, Qatar extracted the least amount of petroleum throughout the period. Qatar’s figures followed a slight fluctuation around 0.5, with a peak of 0.8 in 2000, and then dropped to merely 0.6 in the final year.
