Well Logging and Seismic Integrated Fracture Prediction

Fracture is significant in fractured reservoirs, which plays crucial roles in in hydrocarbon accumulation and migration. And its complexity and heterogeneity contribute that fracture prediction is becoming an increasingly heated topic in both the academia and oil industry. In order to overcome the disadvantage of single prediction methods whether depending on well logging or seismic data, a novel approach of integrating both well logging fracture identification and seismic fracture prediction is presented in this paper, which makes use of both traditional well logging data and post-stack seismic data. Various kinds of information including drill cores, interpreted oil layers and lithology are used to demonstrate our well logging fracture identification method in this paper. With the reliable identified well fractures, the research is moved further by the combination of seismic edge detection. According to the application in a China typical fractured igneous reservoir, it is effectively proved that all of our novel fracture prediction flows is feasible and the fracture can be described in a more accurate and direct way than ever. As a result, the novel fracture prediction approach integrating both well logging and seismic data is promising and will gain more concentration in future.
