Geophysical and Geological Reservoir Characterization of the Devonian Shales of the Appalachian Basin: Application of Single-Fold Seismic Data, Natural Fracture and Lithological Characterization of the Comprehensive Study Wells, and Preliminary Geologic Study, GRI Experimental Development Well Site Selection Area. Annual Technical Report, July 1990-July 1991

摘要

The reprocessing and reinterpretation of single-fold seismic data, using modern methods, improved the imaging of deep structure of a portion of north-central West Virginia. Benefits of single-fold seismic data to hydrocarbon producers include: (1) relatively inexpensive means of identifying deep structures above which productive trends may be found, (2) aid to resolution of multi-fold seismic correlation difficulties, and (3) as an aid in locating areas for new seismic data acquisition. Detailed core descriptions, in digital form, allowed placement of the cored Comprehensive Study Wells in context to regional facies. Core description data also assisted in the validation of lithologies calculated from logs. Natural fracture description and measurement led to improved understanding of the association of fractures and structure.
