The bar chart illustrates Angola’s crude oil production output over the period from 1980 to 1999, quantified in thousands of barrels per day.
Overall, the data reveals a significant upward trend in crude oil production throughout the specified years, with noteworthy peaks and a plateau towards the end of the period.
In 1980, Angola’s crude oil output stood at 150,000 barrels per day, a figure that remained unchanged through 1981. However, a gradual increase commenced in 1982, culminating in production reaching 200,000 barrels daily by 1983. The progression in output continued steadily, advancing to 250,000 barrels in 1984, followed by an ascent to 275,000 barrels in 1985 and 300,000 barrels in 1986. By 1987, production rose to 325,000 barrels, and by the end of the 1980s, it peaked at 400,000 barrels in 1989, showcasing a remarkable growth of 250% over the decade.
The upward trajectory persisted into the 1990s, with production increasing to 450,000 barrels in 1990. Subsequently, output stabilized at 500,000 barrels from 1991 to 1992 before continuing to rise to 525,000 barrels in 1993. A further gradual increase was observed, as production reached 550,000 barrels in 1994 and heightened to 600,000 barrels in 1995. The highest production occurred between 1996 and 1999, when output mirrored at 750,000 barrels per day in both 1998 and 1999, indicating a substantial escalation and eventual stabilization in crude oil production within this final segment.
