Correlation of the seismic data in time domain (on the left) and the well data in depth domain (on the right), also called seismic-well tie. A synthetic trace derived from the sonic and density logs and the corresponding well tops, derived from a lithology log, were shifted to match it with the reflectors of a seismic trace, extracted from the 3D seismic near the well paths, and the interpreted horizons in time. The seismic-well tie was improved by visual examination and manual stretching and squeezing of the synthetic trace to extract a wavelet and to generate a time-to-depth (TDR) curve for the corresponding well
