GlobalData: best performing wells in Permian break-even at as low as US$22/bbl

During the last three years, companies operating in the Permian basin have drilled much longer laterals and used substantially more complex well completion design in their newer wells with the aim of reaching higher initial production (IP) rates. Well lateral lengths in the Permian have increased in average by more than 1500 ft since 2016 to approximately 7500 ft by the end of 2017, says GlobalData.

An analysis of recent wells for 26 operators in the Permian basin indicates a break-even oil price range from US$21 to US$48/bbl with lateral lengths ranging from 4500 ft to 10 500 ft.

Currently, five Permian operators, EOG Resources, XTO Energy, Pioneer Natural Resources, Concho Resources, and Chevron are the companies with the lowest oil break-even price. For these operators, well lateral lengths vary from 7560 ft to 10 500 ft and an oil break-even price for their most representative type well is less than US$26/bbl. The estimated ultimate recovery (EUR) for such wells exceed 1000 million boe and their IP rate is in the range of 1260 boe/d and 1917 boe/d.

Svetlana Doh, Oil & Gas Analyst at GlobalData, says: “Longer laterals do not necessarily translate into high productivity. For instance, QEP Resources has an average lateral length of around 7200 ft, but an IP rate of around 730 boe/d. By contrast, the wells drilled by EOG have approximately the same length, 7560 ft, but yield twice higher initial rates.

“The reason for such a difference is generally related to a completion design incorporating more fracturing stages and the amount of proppant injected. Recent wells drilled by EOG have approximately 2400 lb of proppant injected per lateral foot, while QEP used 1300 lb of various type proppant per lateral foot.

“All 26 operators included in this analysis have new wells that break-even below a price of US$50 per barrel. Nonetheless, some operators evidence the possibility of reaching even higher well returns with break-even values below US$25 per barrel.”
