when technology meets the geological vision
New discoveries are based both on past 75 years experience and on new geological concepts, that is, on a new “geological vision”.
The development of new concepts is based on a deep understanding of field and laboratory hard data, advanced geological numerical and experimental modelling and the cumulative, shared knowledge of the geological community.
Successful exploration is not a matter of chance, but the result of appropriate risk management, analysis of unexpected outcomes and the optimization of the geological evaluation based on a deep understanding of the earth.
Global e&p activity in new areas and new concepts requires greater technical flexibility and integration.
As a world leader in interpretative and geological modelling technologies, eni e&p combines G&G data, geological field surveys and novel proprietary technologies from our in-house laboratories to produce comprehensive integrated studies.
