A joint Petroleum Exploration Society of Great Britain/London Geological Society event discussed how geological assets, both physical and digital, can be held for the long term. New UK regulations have clarified operators' responsibilities and the UK is planning a National data repository. Attendees also learned of PGS' big seismic data solution, use of 'Linq' to communicate between IT and executives, of machine learning in large text collections and on digitizing ExxonMobil's thin sections.
