The problem of oil reservoirs prospecting in the Bazhen formation in the West Siberia is exciting and difficult. Exciting - because the Bazhen formation’s oil reserves are estimated up to 7 billion tons and difficult - due to its fracture-cavernous nature. The results of oil reservoirs forecasting in the Bazhen formation of the Salym oilfield are presented. The forecast is based on using scattered seismic waves extracted from the 3D multichannel seismic data by the original CSP prestack migration method. Shown that this approach enables to obtain much more reliable reservoirs forecasting map and reservoirs model than conventional processing and interpretation methods.
