Can you please give me a clear explanation of how can I create a time depth chart with IHS Kingdom both for onshore and offshore data. Also would be great if you share any PDF or so. I already have measured depth and corresponding TWT. When selecting MD, does the first row on TD chart should always be 0 TWT and 0 m? For example if I have a borehole located at +80 m and the corresponding TWT=0.2s, when I enter MD=0 and TWT=0.2 IHS Kingdom gives error. What is the difference between TVD seismic and MD? I have seismic datum=0m both for onshore and offshore.
Thank you very much
