CONVERSAZIONES were held this year on 6 May and 24 June. At the first conversazione twenty-four exhibits and a film were shown. Dr P. E. Kent, F.R.S., and Mr P. J. Walmsley of The British Petroleum Company Limited arranged an exhibit demonstrating the latest progress in the exploration for hydrocarbons in the North Sea. The established gas fields and the recently discovered oil fields were shown on maps together with sections which illustrated their structure. Seismic sections and geological interpretations were exhibited to show the type of information being obtained in the North Sea and the structural complexities which arise. A scale model of one of the semi-submersible drilling outfits used in North Sea exploration was on display together with a sample of British North Sea oil.
