Haynesville Regional Shale Study

The Haynesville is a complex stratigraphic sequence that was deposited during the Upper Jurassic within a limited and stratigraphically variable area in the Northeast Texas / North Louisiana section of the Gulf Coast Mesozoic Basin. The thickness and quality of this highly prospective interval is directly related to its depositional position with respect to basement rifting and salt thickness as well as its presence within restricted euxinic areas. This reservoir is further impacted by several transgressive / regressive events plus turbiditic influxes that serve to impact the original development of this complex carbonate / siliceous mudstone sequence. This project focuses on the core area of the Haynesville play along the Texas–Louisiana state line and extends outward toward the known limits of this unconventional play. The heterogeneity of this sequence, when combined with its thermal history and geopressure, has a direct impact on the reservoir quality of the Haynesville both with respect to its matrix qualities as well as its fracture stimulation compatibility.

This study provides a detailed petrophysical and geological analysis of more than 40 Haynesville wells that identifies and quantifies the hydrocarbon column for each well and confirms the stratigraphic validity of the area. It incorporates NULOOK Shale Vision, NUVIEW 3D Reservoir Vision and NUSTIM GeoTextural properties modeling to connect the textural attributes of the wells to one another.
