The review, carried out by Investis, evaluated the corporate websites and use of digital media of 1,400 companies, scoring them out of 100 for usability, corporate governance, corporate social responsibility (CSR), investor relations, use of mobile and use of social media.
ENI scored highly across all of these metrics, with a total score of 79, and was found to be particularly successful at communicating its strategy and business model.
Shell came second across all metrics, with BP in third place.
By comparison, the Israeli company Delek Drilling scored 20 out of 100, while Soco International, a British FTSE250 company, scored 28.
Investis found that integrated oil and gas companies scored more highly than upstream companies involved in prospecting and drilling for resources.
Upstream companies scored poorly for interaction with the media as well as use of social media with a third of those surveyed failing to provide contact details for a media spokesperson.
Investis also ranked a wider sample of 1,400 businesses across a variety of sectors on their digital presence, with ENI, Shell, BP and Statoil all featuring in the top ten.
Marcus Fergusson, Investis’ research director, said: "The demands of customers and investors are forcing companies to take their digital communications more seriously. We fully appreciate that some companies will embrace the new tools faster than others."
