The post that follows relies heavily on the previous work of both Paul Pukite (aka Webhubbletelescope) and Jean Laherrere and I thank them both for sharing their knowledge, any mistakes are my responsibility.

In a previous post I presented a simplified Oil Shock model that closely followed a 2013 estimate of World C+C Ultimately Recoverable Resources (URR) by Jean Laherrere of 2700 Gb, where 2200 Gb was from crude plus condensate less extra heavy oil (C+C-XH) and 500 Gb was from extra heavy (XH) oil resources in the Canadian and Venezuelan oil sands.

In the analysis here I use the Hubbert Linearization (HL) method to estimate World C+C-XH URR to be about 2500 Gb. The creaming curve method preferred by Jean Laherrere suggests the lower URR of 2200 Gb, if we assume only 200 Gb of future reserve growth and oil discovery.

Previously, I have shown that US oil reserve growth (of proved plus probable reserves) was 63% from 1980 to 2005. If we assume all of the 200 Gb of reserves added to the URR=2200 Gb model are from oil discoveries and that in a URR=2500 Gb, oil discoveries are also 200 Gb, then 300 Gb of reserve growth would be needed over all future years (we will use 90 years to 2100) or about 35% reserve growth on the 850 Gb of 2P (proved plus probable) reserves in 2010. I conclude that a URR of 2500 Gb for C+C-XH is quite conservative.

A problem with the Hubbert Linearization method is that there is a tendency to underestimate URR.

The EIA’s Questionable Numbers

Ron Patterson 509 Comments

The EIA’s, on June 30th, published its Petroleum Supply Monthly. I Think their numbers are just way too high. I compared them with the EIA’s Weekly Petroleum Status Report. The chart below shows the Results.

EIA Post 1

I averaged the weekly numbers and converted them to monthly data. They were pretty close for the first three months of 2014 but then they begin to diverge. Of course they were much closer earlier but in the Petroleum Supply Monthly has, over several months, been revised upward. The Weekly Petroleum Status Report is never revised.

In April, the Petroleum Supply Monthly shows US C+C production 322,000 barrels per day above the weekly average of the Weekly Petroleum Status Report.

Texas RRC March Production Data

Ron Patterson 569 Comments

The Texas RRC is out with their latest Oil and Gas Production Data. Looks like oil production has leveled out with March production pretty much level with February. All RRC data is trough March 015.

Texas Crude Only

I always show the last 6 months or the RRC data in order to get a pretty good indication of which way data production is moving. From the data you can see that December was a very good month but January was just awful. February was a lot better and March was about the same as February.

Dean 1

The chart above was created by Dean Fantazzini, PhD, of the Moscow School of Economics. He has developed an algorithm which predicts what the data will reflect after the final data has come in. His data suggests that Texas crude has plateaued.
