EIA’s Annual Energy Outlook and the Seneca Cliff
The scenario above shows an Oil Shock Model with a URR of 3600 Gb and EIA data from 1970 to 2015 and the Annual Energy Outlook (AEO) 2016 early release reference projection from 2016 to 2040. The oil shock model was originally developed by Webhubbletelescope and presented at his blog Mobjectivist and in a free book The Oil Conundrum.
The World extraction rate from producing reserves must rise to 15% in 2040 to accomplish this for this “high” URR scenario. This high scenario is 100 Gb lower than my earlier high scenario because I reduced my estimate of extra heavy oil URR (API gravity<10) to 500 Gb. The annual decline rate rises to 5% from 2043 to 2047 creating a “Seneca cliff”, the decline rate is reduced to 2% by 2060.
The scenario presented above uses BP’s Energy Outlook 2035, published in Feb 2016. This outlook does not extend to 2040, maximum output is 88 Mb/d in 2035 at the end of the scenario. This scenario is still optimistic, but is more reasonable than the EIA AEO 2016. Extraction rates rise to 10.6% and the annual decline rate rises to 2.5% in 2042 and is reduced to under 2% by 2053.
A problem with the BP Outlook is the expectation that US light tight oil (LTO) output will rise to 7.5 Mb/d from 2030 to 2035, the BP forecast for US LTO from 2013, 2014, 2015, and 2016 is shown below.
A more realistic forecast would be a peak of 6 Mb/d in 2022 with output declining to 3 Mb/d by 2035. The scenario below shows roughly what World output might be with this more realistic, but still optimistic scenario. There is a plateau in output at 85 Mb/d from 2025 to 2030 with annual decline rate peaking at 2.1% in 2044 and then falling under 2% per year from 2048 to 2070.
