Title: The use of high-resolution aeromagnetic surveys to delineate basement controls on thin-skinned, fractured, tight gas reservoirs: Examples from the Piceance Basin

Abstract

An analysis of recently-acquired, high-resolution aeromagnetic data, integrated with structural, production history, and seismic analyses of the Piceance Basin identified a strong correlation between basement structures and fractured tight gas reservoir production trend located in thin-skinned structures. Detailed reservoir characterization of fields associated with Piceance Basin thin-skinned structural traps reveals the importance of fracture-controlled production in these fields. Most importantly, many fields thought to lack fractures, demonstrate insufficient permeability for economic production unless fractures are present. Seismic interpretation indicates that many thin-skinned structures in the Piceance Basin are related to deeper-level basement features. The southwestern basin, in marked contrast, contains E/W-oriented folds such as the Debeque, Bull Creek (new), and Garmesa anticlines. Similar E/W trends are exemplified in the northwest and north-central basin by the Rangely and White River Dome anticlines, respectively. Aeromagnetic surveys, integrated with critical information about regional structure and fractured reservoir production trends, represent a relatively inexpensive method to document potential fractured tight gas reservoirs. In basins where fractured reservoirs are related to small-scale, thin-skinned structures controlled by basement deformation, aeromagnetic surveys permit a rapid first-order screening for potential exploration targets. In mature basins, aeromagnetic surveys may reveal previously-overlooked, small-scale structures containing fracture-controlled production, or overlie deepermore » reservoir plays not previously tested.« less
