The Permian Basin
The Permian Basin is located in western Texas and southern New Mexico, generally referring to a combination of the Midland Basin and the Delaware Basin. According to the US Energy Information Administration (or EIA), the Permian Basin produces the most crude oil in the US.
Rig counts in the Permian Basin can gauge the drilling activities of upstream companies. These companies include Chevron Corporation (CVX), Cabot Oil & Gas (COG), Occidental Petroleum (OXY), and EOG Resources (EOG). Together, Occidental Petroleum and EOG Resources form 7.4% of the SPDR S&P Oil & Gas Exploration & Production ETF (XLE).
Comparing Permian rig counts with other rigs
Currently, there are 922 working oil rigs in the US. The Permian Basin has 328 of these rigs, more than any other region. The Eagle Ford Shale has 129 active oil rigs, the Williston Basin has 108, and the Mississippian Lime has 44.
In the past year, Permian Basin activity declined because it lost 176 oil rigs. The Permian Basin rig count is now at its lowest level in the last four years.
The Williston Basin lost 69 oil rigs. The Williston Basin includes the Bakken Shale, one of the most prolific crude oil shale plays in the United States. The Eagle Ford Shale in East Texas lost 56 oil rigs, while the Cana-Woodford Shale in Oklahoma’s Anadarko Basin added seven oil rigs.
Last week, the Permian Basin’s oil rig count fell by 24 over the previous week’s count. This was the 13th straight weekly decline in the Permian oil rig count and a 7% decline from the previous week. Overall, the weekly US crude oil rig count was down 6%. The Permian Basin rig count fall moderated for a couple of weeks before the rate of decline picked up again last week.
Horizontal rigs on the rise in the Permian Basin
Horizontal rigs account for 71% of the Permian Basin’s total rig count. Vertical rigs account for 27%, and directional rigs account for ~2% of the total. By way of comparison, on March 9, 2012, there were 489 rigs, and only ~22% of the rigs were horizontal. At the time, rigs in the Permian Basin were mainly vertical, accounting for ~73% of rigs there. Directional rigs accounted for ~5%.
