Fortunately, I received fan mail. Thats right, after 20 years IGeophysical Operations Adviserhave had two responses from readersNote: Photographs supplied by so that the total letter count since myJohn R Hughes Geophysical Pty Ltd JohnHughesfirst article is now approaching double figures. Neither of these replies were to claim the prize offered in the last issue, which is still available (I could interpret this as the readers dislike of competitions or red wine but it may indicate a lack of readers.) Here are the letters:Hi Mick,Just read your Preview article. So true, but you forgot to mention that although we had lots of TA, secretarial and drafting support, we had to do the complete range of actions involved in the seismic workflow from instrument testing, supervising micro arrays in the field for noise analysis to decide on the geophone array, acquisition QC (both offshore and onshore), static modelling, processing QC (including your own velocity picking) before we finally got to interpretation. These days all I do is decide on the area of interest, sit in on the processing meetings, and interpret the final data before, as you say, make copious PowerPoint displays and presentations.Finally,I agree with your final assessment of FWI (and I would add tomography) along with anisotropic input has changed the game significantly.JuNE 2020 PREVIEW 30'
