Evaluation and Influence of Structural Trends from Magnetic and Gravity Data in the Texas-Louisiana Haynesville Play

A number of individual elements need to be present to produce a viable hydrocarbon system in both conventional and non-conventional shale plays. Key to this is the influence of both regional and localised fault and fracture patterns, and examples of these and their correlation with production from the Texas-Louisiana Haynesville area are presented. This paper demonstrates how powerful a tool high resolution gravity and magnetic data are in the identification of structural trends and fracture patterns in the Haynesville area. Analysis of these data helps define the trends that strongly influence the production, permeability and depositional trends in the Haynesville and other key stratigraphic units in the basin. Understanding of these trends, their inter-relationship and their influence on production can help focus an exploration programme.
