Heavy oil production decline
Oil and gas production rates decline as a function of time; loss of reservoir pressure, or changing relative volumes of the produced fluids, are usually the cause. Fitting a line through the performance history and assuming this same trend will continue in future forms the basis of DCA concept. The decline curve for tight oil wells can be broken into three parts: early peak production where the declines are steepest, a transition period where production and declines slow, and terminal decline where the decline rate goes down a bit and the curve flattens. Decline curve analysis is a long established tool for developing future outlooks for oil production from an individual well or an entire oilfield. Depletion has a fundamental role in the extraction of finite resources and is one of the driving mechanisms for oil flows within a reservoir. For the short and medium-term, oil production decline occurs in a predictable manner based on geological circumstances, governmental policies, and engineering practices. The shape of the decline curve varies depending upon whether one considers a well, a field, or a set of fields.
A recent paper of Robelius’ in Energy Policy (Giant oil field decline rates and their influence on world oil production) states that currently the average (mean) annual decline for the world’s giant oil fields is ~6.5%, with a production weighted average of 5.5%. He also notes that offshore giant fields decline at almost 3 times the rate of onshore fields.

Russia, which
The most recent forecasts published by the US Energy Information Administration show US oil production increasing steadily. The February Short-Term Energy Outlook sees the output from US wells rising from 11.9 million barrels per day at the end of 2018 to 13.5 million barrels per day by the end

Growing production in North America has resulted in declining imports of oil from overseas sources. U.S. net imports of crude oil declined from 10.0 million barrels

12 Jul 2018 California drops to sixth in monthly crude oil production. The amount of crude oil produced in the Golden State has been declining since the 15 Nov 2018 Crude oil production sinks in Maduro's Venezuela. Barrels/day. 12 Sep 2018 US oil production declined -- but not as dramatically as feared. And when In late 2015, Congress lifted the 40-year ban on exporting crude oil. 31 Aug 2018 US 2017 oil production is from EIA MER: 9.4 Mb/d for crude, 13.1 Mb/d for crude -second model: production with fast rise and slow decline. 20 Aug 2018 In contrast, production on federal lands declined each year from 2009 through 2017. Much of the decline can be attributed to offshore production
Driving that view at the time was the expectation that U.S. oil production would decline by 940,000 barrels per day this year, which represents a 10.1% year-over-year decrease, while worldwide declines would add up to a 3.3% decrease in production. The 2 million barrel a day drop in total production since the end of 2018 has all been medium and heavy, with little additional light oil to offset the decline in that period. But over the longer In the Caribbean, mismanagement of oil industries means that heavy oil production from two key countries is also dropping fast. Mexico and Venezuela are both in long-term decline and the U.S. crude oil production broke 10 million barrels a day in November for the first time since production peaked in 1970, at the start of a decades long decline. The U.S. is the world's third The decline curve for tight oil wells can be broken into three parts: early peak production where the declines are steepest, a transition period where production and declines slow, and terminal decline where the decline rate goes down a bit and the curve flattens. Paper I: A decline rate study of Norwegian oil production Norway has been one of the two major producers in the North Sea as well as the world’s third largest oil exporter.
