Procedure

1. Create a new study. In the Seismic interpretation toolbar tab > Seismic-well calibration group > click on the Seismic well tie button (Figure 1).

2. In the window that appears, select Synthetic generation as the Study type, and the name of the well or hole.

In the Input tab: 

a) Select a new TDR or use the one currently applied for the well.

b) Choose a wavelet to be convolved with the reflection coefficient, or create a new one by clicking the button to the right of the dropdown box. 

c) Identify the seismic profile associated with the well being studied.

d) For calculating the Reflectivity coefficient, the Sonic velocity and density method is often used. From the corresponding dropdown lists, select the logs to be used, preferably those that have been conditioned and calibrated, especially for the sonic log.

e) Expand the Advanced settings. In cases where the input logs are of different depth coverage, there is the option to use the Gardner's equation to generate a segment of the synthetic seismogram using only one log.

3. In the Output tab
