It was gratifying to see that, despite the challenges inflicted by the pandemic this past year, technologies in the seismic world continued to advance. As an example, the machine-learning theme again received considerable focus.
As I reviewed all the SPE seismic papers this time, the most noticeable thing was the diversity of themes and case histories that were covered.
Thus, in addition to selecting three papers to be synopsized this year, I expanded the list of recommended readings to showcase that diversity. For instance, gravity and electromagnetics (and their integration with seismic) are also featured. I hope you will find this broad range of topics useful.
