Welcome to the third tutorial in this series. Evan Bianco has put together a terrific look at 1D synthetic seismograms — the critical connections between well data and seismic data that make geologic interpretation possible. Most of us use proprietary software for this part of the workflow, but do you really know what's going on in there? My challenge is: Take a couple of hours, install IPython from ipython.org, and see if you can work your way through Bianco's Notebook at github.com/seg/tutorials — I guarantee you will learn something. If you get stuck, please reach out to him.
