To estimate the amount of US oil produced between 1940 and 2000 by numerical integration
Use the midpoint rule to estimate the amount of US oil produced
Midpoint Rule:
The midpoint from the graph are:
Year | 1945 | 1955 | 1965 | 1975 | 1985 | 1995 |
No of barrels in milllios/day | 4.5 | 6.2 | 7.5 | 9 | 9 | 6.5 |
As the number of intervals are n = 6,so the length of each
interval x is expressed
as
Integration:
So the results is 427 * 106 (millions per day)
As the number of days per year is 365
Total production = 427 * 106 * 365 = 1.6 * 1011
So the number of barrels of US oils produced is 1.6 * 1011

U.S. crude oil and natural gas production increased in 2018, with 10% fewer wells 2/3/2020 WASHINGTON - In 2018, while production was increasing, the total number of wells producing crude oil and natural gas in the United States fell to 982,000, down from a peak of 1,035,000 wells in 2014. This increase in production, despite the decline in the number of wells, reflects advances in technology and drilling techniques. The U.S. Energy Information Administration (EIA)’s updated U.S. Oil and Natural...
