Top Producing Counties - Areas - 2013 - Fixed - US Oil Production

The 80/20 rule, also known as the Pareto Principle, is a concept used to describe a highly nonlinear relationship between cause and effect. In other words, a minority of the causes (20%) account for a majority of the results (80%).

The spatial distribution of US oil production follows a version of the 80/20 rule. In this case, we’ll call it the 52/2 rule. 52% of all US oil production (as well as 20% of all US natural gas production) in 2013 came from these 20 counties, which make up only 2% of all producing counties.

TopProducingCounties - List - US Oil Production

As you can see from the Type column in the table above, I’m taking some dramatic license with the term county. There are no counties in the Gulf of Mexico (GoM), but the Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE) defines Protraction Areas which subdivide the gulf. Also, most of Alaska is lumped into a single “Unorganized Borough,” so I’m using US Geological Survey (USGS) quadrangles instead (https://ardf.wr.usgs.gov/quadmap.html).

Conventional US Oil Production Tops the List

One surprising result is that, for all the attention unconventional oil production has been receiving, the top four spots all go to conventional production areas in the GoM, Alaska, and California.

Unconventional is Coming on Strong

Unconventional areas begin to dominate starting at the 5th spot with McKenzie County, in the heart of the Bakken/Three Forks play.

The resurgent Permian Basin is represented by three of the counties on the list: Eddy (#8), Lea (#16), and Andrews (#17). These areas are a mix of legacy conventional production and newly added unconventional production.

Summary

This list illuminates where American oil production is currently coming from, both across the country and within the key producing areas. It is striking that so much of our production comes from a relatively small geographic space. We can expect this list to continue to change in 2014 as unconventional areas continue to ramp up, while some older areas continue their decline.
