Effective hydraulic fracturing is critical for generating permeability within the Barnett Shale of the Fort Worth basin (FWB). Therefore, knowledge of the nature of the induced and natural fractures, faults, and collapse features that may form conduits to the underlying Ellenburger aquifer is vital. We use coherence and curvature seismic attributes, which are sensitive to faults, fractures, and collapse features, to map sedimentary features. We then integrate high-resolution aeromagnetic (HRAM) data with the seismic attributes extracted along the Ellenburger Formation and the top of basement from the north-central portion of the FWB, thereby linking features in the Precambrian basement to shallower sedimentary structures. HRAM-derived maps, designed to enhance basement structures, confirm that much of the sedimentary faulting is basement controlled. Specifically, attribute lineaments are aligned parallel to HRAM anomaly lineaments, consistent with regional tectonics. The northeast-southwest and northwest-southeast orientations of folds and faults in the sedimentary section parallel the northeast-trending Ouachita orogenic belt and the northwest-trending Muenster arch, which in turn correlate with reactivated Cambrian/late Precambrian basement faults. Mapping such features can aid in the design of the hydraulic fracture program and ability to predict structurally deformed areas of the basin.
