EIA Liquids Reserve Estimates

This follows on from Part I, which looked at EIA reserves and revision estimates for US as a whole and the GoM, and concentrates on the on-shore tight oil and (below)gas producing regions.

The EIA issues revision data by whole states or state districts rather than by basin, so some of the reserves and production, but a small proportion, will be from conventional reservoirs. It does give total reserves for each shale basin but not the changes, and I didn’t go to the trouble of pro-rating everything against that. Its data only goes through 2019; the 2020 update will be out in December or January.

The regions for each basins used are Permian – Texas Districts 7C, 8 and 8A and East New Mexico; Bakken –  North Dakota and Montana; Eagle Ford – Texas Districts 1, 2, 3 and 4 Onshore; Niobara –  Colorado; Marcelus – Pennsylvania and West Virginia; Utica –  Ohio; Haynesville – Louisiana South Onshore and Texas District 6; Barnett – Texas Districts 5, 7B and 9; Woodford – Oklahoma ; Fayetteville – Arkansas.

The story here is of a gradual decline in the size and importance of most of these (once) large independents. Their combined reserves and production is not sizeable compared to the super majors and majors but their history may be indicative of what is coming the way of the larger companies. All but one of these companies is American owned. Most have or had holdings in shale or oil sands but many have sold off most of these and chosen to concentrate on a shrinking core business. There is probably a fuller picture to see if their financial performances, such as debt loads or share buy back schemes, were also considered but that’s a bigger job than I’m prepared for or capable of.
