This interactive presentation contains the latest gas production data from 5,059 horizontal wells in the Haynesville, that have started producing since 2009/2010, through January 2019. The post on the Permian has been delayed to later this week.

Gas production in the Haynesville rose by more than 2 Bcf/d in 2018 to well over 8 Bcf/d, which was the strongest growth since 2012, breaking the previous record set 6 years earlier. The apparent drop in the last 2 months visible is due to missing production data from new wells, which will become available over time.
The main reason behind this fast growth is that about 30% more wells were completed in 2018 than in the previous year. Well productivity made substantial jump in 2016 (see “Well quality”), followed by a small one in 2017, but did not improve further in 2018, based on preliminary data. New wells are on a path to recover close to 6 Bcf in the first 2 years, on average, a level that earlier wells are unlikely to reach in their lifetime.
Proppant loadings have increased the most in this basin, over the last couple of years. On average, well above 20 million pounds of proppants were injected into wells completed in 2018, versus less than 5 million pounds in 2012.
The final tab shows the production and location of the top 5 operators, including Chesapeake and Indigo, both operating over 1 Bcf/d.
The ‘Advanced Insights’ presentation is displayed below:
This “Ultimate Return” overview shows the relationship between production rates, and cumulative recovery, over time. Wells are grouped by the year in which production started.
This chart also shows the major improvement in well productivity. Newer wells peak at double the rate than wells from a couple of years ago, and their initial decline is less steep.
However, also these more recent wells appear to follow a similar decline after this initial period, based on preliminary data. This is more visible if you change the “Show wells by” selection to ‘quarter of first flow’, which displays more granular and recent data.
Later this week we will have a post on the Permian. Today at noon (EST) we will present a briefing on all the major gas basins in the US, in our ShaleProfile channel on enelyst. Registering is free: enelyst registration page.
Production data is subject to revisions. For this presentation, I used data gathered from the following sources:
- The Louisiana Department of Natural Resources
- Texas RRC. Production data is provided on lease level. Individual well production data is estimated from a range of data sources, including regular well tests, and pending lease reports.
