The Haynesville Shale Play has been a focus of activity since its discovery in 2005 and quick activity ramp-up from 2007 forward. Currently, rig activity in the play is waning in response to natural gas prices and it gives active operators an opportunity to reflect on lessons learned and what remains on the road ahead. After hundreds of wells have been drilled, the play is still early in its life cycle. Many learning’s are realized. Resource definition, geomechanical relationships and how the rock responds to fracture stimulation are largely understood. Mapping techniques yield useful and important insights on how hydrocarbons are emplaced in the rock and how recovery can be achieved. It is know that stimulation evolution and implementation of certain production techniques are successful in increasing the well performance. More subtle relationships on how water interacts with the rock matrix and its impact on well quality are evolving. The question of optimum drainage remains elusive and solution to this problem resides in defining the interrelationship of zonal targeting, fracture stimulation size, well density and production technique. These relationships combine to deliver differing recovery and economic outcomes and reservoir simulation modeling is a powerful tool in unraveling the correct answer. Future efforts by Haynesville operators will be directed at fully understanding the actual effect of fracture propagation in the Haynesville reservoir and how the reservoir is being effectively drained by the surface are created by these stimulations.
