Abstract:

The possibility to predict fracture systems in crystallized basements by seismic method is always of high priority for exploration of hydrocarbon in sedimentary basins offshore Vietnam. Most of wells with basement targets were designed based on the seismic data analysis. However, interpretations of these fracture systems have always been difficult because of the low signal to noise ratio inherent with the basements at depth. Majority of the noise come from random noise and multiple reflections from clastic layers above. If the noise can be effectively suppressed it would be very helpful to better determine the fracture systems and therefore reduce the drilling risk. In this article the author suggests a method to suppress coherent noise in the basement by application of F-K filtering technique. The results show that signatures of fractures in the basement become much clearer after the F-K filtering
