The provided line graph illustrates the fluctuations of Chinese production and consumption of the oil over a period of 24 years, commencing in 1982.
Overall, the figures of both oil producing and consuming recorded an upward trajectory. However, while the Chinese oil-making industry saw a gradual growth, it seemed that the volume of oil used increased significantly.
In 1982, both the producing and consuming oil were at around 2 million barrels. The trend of oil using was nearly stable compared to the starting statistic in the subsequent 8 years, followed by a sharp surge to approximately 4 million in 1994. In contrast, the oil-producing industry witnessed a million increase in 1986, after which maintained at about 3 million barrels via the rest of the initial quarter.
Subsequently, the volume of oil processing saw a stable pattern by over 3 million, then it witnessed a slight surge to nearly 4 million barrels per day in 2006. Meanwhile, the needs of oil seemed to increase that its figure ascended sharply, peaking at over 6 million at the same time of the period.
