| Abstract |
Geometric attributes such as coherence and curvature have been very successful in delineating faults in sedimentary basins. While not a common exploration objective, fractured and faulted basement forms important reservoirs in Mexico, India, Yemen, and Vietnam. Because of the absence of stratified, coherent reflectors, illumination of basement faults is more problematic than illumination of faults within the sedimentary column. In order to address these limitations we make simple modifications to wellestablished vector attributes including structural dip and azimuth, amplitude gradients, and maximum and minimum curvature, to provide greater interpreter interaction. We apply these modifications to better characterize faults in the granite basement of the Cuu Long Basin, Vietnam, that form an unconventional, but very important oil reservoir. ©2008 Society of Exploration Geophysicists |
