Improving well to seismic ties; a South African case study

The starting point for seismic interpretation and detailed seismic reservoir characterization is typically a good quality well to seismic tie. A standard approach is to convolve an assumed wavelet with the reflectivity series determined from the acoustic impedance log. The resulting well to seismic tie is in many instances poor. This could be due to seismic processing problems and/or inappropriate calibration of the log data and subsequent synthetic seismic trace generation.
