Integration of the Reflected and Diffracted Waves to Increase the Reliability of Predict Fractured-Porous Reservoirs

The traditional wide-azimuth seismic surveys with small offsets provide irregular depth illumination of the object and from the specular-reflected waves and by the use of diffracted waves, making it very difficult to share when their drill oil and gas reservoirs. Modern full-azimuth survey with large offsets (up to 5-10 km and more) with high expansion and a relatively uniform distribution of the deletions provide unique opportunities for sharing the information obtained from the mirror-reflected and diffracted waves at their integral interpretation for the study and mapping of fractured -porous collectors. The report shows the possibilities of interconnecting the mirror-reflected and diffracted waves according to the full-azimuth seismic data to improve the reliability and detail mapping of fractured-porous hydrocarbon reservoirs. The examples of the effectiveness of this technology in certain fields of the CIS
