Juan Soto was a member of the Technical Committee for the virtual Third EAGE Eastern Mediterranean Workshop hosted in Larnaca, Cyprus on December 1-3, 2021.  During the meeting Juan maintained various talks with colleagues from ExxonMobil, Chevron, and PGS.




Gillian Apps was a member of the Technical Committee for the SEG/EAGE Virtual Workshop on The Deliberate Search For Stratigraphic Traps: Has It Come Of Age? 
Dr Donald Christie, former PhD student of Frank Peel and Gillian Apps, gave an invited and well-received talk, entitled "Forward Stratigraphic Modelling with Onlapse-2D for Reservoir Prediction, offshore Sureste Basin, Mexico". Alex Bump from BEG's Gulf Coast Carbon Center also gave an invited talk, entitled "Stratigraphic Traps for carbon Storage: Rethinking Risk and Success", which inspired a great deal of discussion.
