Integrating 3D seismic curvature and curvature gradient attributes for fracture characterization: Methodologies and interpretational implications

摘要: ABSTRACTIn 3D seismic interpretation, curvature is a popular attribute that depicts the geometry of reflectors and has been widely used to detect faults in subsurface; however, it provides only part solutions subsurface structure analysis. This study extends algorithm new gradient integrates both algorithms for fracture detection using test data set over Teapot Dome (Wyoming). In fractured reservoirs at formed by tectonic folding faulting, helps define crestal portion associated with strong amplitude high oil productivity. contrast, regional northwest-trending cross-regional northeast-trending lineaments are weak low concert previous reports from image logs, cores, outcrops, an integrated analysis suggests t...
