Abstract

Optimizing the methodology for stimulating a shale play in early development is always a goal of the operators involved. With the Haynesville shale reservoir now well into its development, with several wells having produced 12 months or more of public production, play-wide trends can help determine which completion methodologies create the best-producing wells. The uniqueness in pressure, temperature, and lithology that characterizes the Haynesville shale creates the expectation that proven techniques of other unconventional shale reservoirs may not necessarily produce the same result in the Haynesville shale. Considering trends developed from cross-referencing completion strategies in laterals with public production, Haynesville well production appears to be heavily dependent on geographic location and total number of hydraulic fracturing treatments performed. Also impacting production are proppant placement strategies affecting conductivity (both concentration and overall volume) as well as the limited-entry clustering technique used paired with the treatment injection rate. To optimize short-term cumulative production as well as production sustainability, Haynesville well-completion strategy must focus on increasing the number of effectively stimulated fractures along the lateral as well as placing a proppant pack that will provide sustained conductivity in the adverse conditions of the Haynesville shale.
