Permian Basin – crude & condensate output refuse to decline; average well configuration & productivity continue to grow

Among the key tight oil plays in the US, those in the Permian Basin have gotten a particular market attention in recent months. Not only crude and condensate output from these plays refuse to decline. Also, average well configuration and productivity continue to grow due to a shift towards the most productive areas of the Basin, together with more economical well completion characteristics.

Looking at the horizontal wells in Midland and Delaware Basins, which were brought on-line in 2012-2016, Figure 1 summarizes the evolution of average proppant use and lateral length per well. Both these metrics increased considerably over that last four years and the average lateral length in the Permian Midland has already exceeded 8,000 ft. However, average proppant use grew more rapidly leading to an increased completion intensity. Back in 2012, approximately 900 and 500 lbs of proppant per feet were pumped in the Midland and Delaware respectively, whereas in Q1 2016 1,400 and 1,500 lbs per feet were observed, respectively. 

 

A natural consequence of boosted well configuration and full-scale development of Wolfcamp and Bone Spring formations resulted in an increased well productivity. Figure 2 shows the distribution of estimated ultimate recovery (EUR) for horizontal wells in the Permian Basin, quarter-by-quarter. Less than 15% of the wells exhibited EURs above 600 thousand boe in 2012-2013. However, what used to be an outstanding well performance in those years has become a standard by 2015-2016 as the share of such wells reached 50-60%. Simultaneously, only 10-20% of the current wells demonstrate EURs below 300 thousand boe, while in 2012-2013 the share of such wells was above 50%. 

Together with a significant unit price reduction, productivity improvements imposed a downward pressure on the wellhead breakeven prices in the tight oil plays of the Permian Basin. Thus, current drilling of dedicated Permian operators remains commercial in the low oil price environment. Figure 3 demonstrates the average wellhead breakeven price for selected operators in the Permian Basin for different years. In 2016, a typical well of the selected companies is commercial at an oil price below 40 USD/bbl. It is worth mentioning that EOG Resources has managed to achieve exceptional well results in Permian Delaware – an area that was not considered their core area of activity before 2015. Latest EOG’s wells belong to the premium part of their drilling inventory and exhibit a breakeven price of around 27 USD/bbl. The second best commerciality is demonstrated by Devon’s wells in 2016, which target the Bone Spring formation, with a breakeven price of around 29 USD/bbl. However, the company decided to drop its last rig in Permian Delaware after drilling only four operated wells in 2016. This confirms the scarce availability of financing, which has become a dominant decision factor in order to continue drilling even in highly economical plays. Nowadays, operators are forced to abandon activity even in some of their best and still commercial plays.
