Within the Haynesville play in east Texas and Louisiana, energy companies target two stacked intervals — the Haynesville and the slightly shallower Middle Bossier. Historically, operators only target a single zone in a development or add one well testing the other zone. However, we recently identified a few larger-scale developments involving four to six wells across the two intervals (Figure 1). The spacing configurations vary between these developments, with some designs directly stacking wells and other designs stagger-stacking wells. Horizontal spacing varies from three to five wells per section between laterals in both designs, and vertical separation between intervals also varies across the play.
With only a few examples of larger-scale, two-zone development in the Haynesville play, there is uncertainty around optimal spacing and well configuration that can only be resolved with more frequent larger-scale development. View our latest Haynesville Play Fundamentals report to dive deeper into this topic and see our view on the potential for stacked pay development within the Haynesville play.
