Editing Hubbert curve (section)

=== Critique ===
After the predicted early-1970s peak of oil production in the U.S., production declined over the following 35 years in a pattern closely matching the Hubbert curve. However, new extraction methods began reversing this trend beginning in the mid-2000s decade, with production reaching 10.07 million b/d in November 2017 – the highest monthly level of crude oil production in U.S. history. As such, the Hubbert curve has to be calculated separately for different oil provinces, whose exploration has started at a different time, and oil extracted by new techniques, sometimes called [[unconventional oil]], resulting in individual Hubbert cycles.<ref name='Hubbert cycle'>{{cite journal |last1=Patzek |first1=Tad |date=2008-05-17 |title=Exponential growth, energetic Hubbert cycles, and the advancement of technology |url=https://www.researchgate.net/publication/228663031 |journal=Archives of Mining Sciences |volume=53 |issue=2 |pages=131–159 |access-date=2018-11-17}}</ref> The Hubbert Curve for US oil production is generally measured in years.
