Processing and re-interpretation of reflective data for area Shatsky Swell allowed confirm and refine<br>construction it’s structures as objects for finding hydrocarbons. Institute of oceanology P.P.Shirshov carried<br>regional refractive profile along these structures of Shatsky Swell. Joint analysis of reflective and refractive<br>data carried prediction of lithological composition of rocks forming Shatsky Swell and composition seismogeological<br>model.
