Haynesville Shale: 16-Year Review of Activity and Well Performance

Abstract Sixteen (16) years of Haynesville Shale development activity has been analyzed. Type curves (production normalized to year zero) were created to understand well performance for various areas, operators and time periods. Changes in well design and production performance trends each year were documented for the top producing counties/parishes and the top thirteen (13) well operators. Drilling activity peaked in 2011 and the current rig count of thirty-three (33) is on a down trend. This analysis shows that well performance trends have reached a maximum point and are now declining. New well reserves peaked in 2019 at 12.5 BCF per well and initial production rates peaked in 2022 at 22,600 MCFD. Current new well drilling economics were also investigated. With current well costs and gas prices, drilling investments show a robust internal rate of return of 30%, a return on investment of 1.6 to 1 and a net present value (PV10%) of over $4.2 million.
