Abstract
Results of fracture and cavernous reservoirs forecasting using scattered waves extracted from multichannel seismic data are presented. The forecast is based on an original prestack migration method – the Common Scattering Point (CSP) method, which enables constructing two independent seismic cubes: a conventional cube with reflectors and a new cube with diffractors – the image of space distribution of acoustic impedance inhomogeneities. The last are joined with fracture or cavernous zones – strong sources of scattered waves. The method was tested on synthetic data and in areas with oil deposits in carbonate and shale rocks.
