The Haynesville Shale, an Upper Jurassic (Kimmeridgian) age calcareous and locally organic-rich mudrock, is one of many prominent shale gas plays in North America. As shale plays increase in importance, the ability to define basin-wide, robust, and stable stratigraphic frameworks using data derived from well-bores becomes increasingly critical. Here, the technique of chemostratigraphy is used to define a stratigraphic framework that extends through ten wells ranging from eastern Texas to northwestern Louisiana. Stratigraphic variations in inorganic geochemistry allow clear differentiation of Haynesville Shale from the underlying Smackover Formation, the Gilmer Lime, and the overlying Bossier Formation. More importantly, however,...

Geology of the Haynesville Gas Shale in East Texas and West Louisiana
This AAPG Memoir on the Haynesville Shale of East Texas, USA, provides an overview of the main geologic, stratigraphic, sedimentologic, geomechanical, micro-seismic and engineering characteristics of the Haynesville mudrocks. Experts on mudrocks from academia, industry, and government contribute with a variety of topics that describe the Haynesville Shale from basin- to nanaoscale, reflecting the dimensions affecting shale-gas assessment and demonstrating the variety of techniques applicable to shale-gas evaluation. The included papers serve not only as examples of shale-gas analyses of the East Texas shale basin employing different techniques, but also are examples of approaches to evaluating shale basins worldwide.
