In 2013 there was a reduction in total water extraction compared to 2012 of 6.5% (equal to about -153M m3) mainly due to the decrease in sea water extraction in the refining sector (where the Gela Refinery alone reduced withdrawals of seawater by more than 137Mm3 due to plant shutdowns).
The fresh water withdrawn, representing 8% of the total water resources used, decreased compared to 2012 (down 3%), due to a decline recorded by the E&P sector (where activities of the Libyan Abu Attifel, El Feel and Wafa fields were stopped or reduced) and Other Activities (where the ethylchloride plant was shut down at the Assemini site). The parameter is also in decline in the sectors R&M (down 2.9%, amounting to approximately -0.5Mm3) and G&P (down 7%, amounting to about -2Mm3).
The percentage of reused fresh water increased overall compared to 2012, reaching almost 80%.
There was further improvement in the performance relating to production water in the E&P sector, with a percentage of re-injection rising to 54% (the best result ever, an increase of more than 10% compared to 2012). Performance was positively influenced by the completion in late 2012 of the Belayim project in Egypt, with a re-injection of 99.5% (equal to 27,265 cubic meters/day).
The concentration of hydrocarbons in the production water fell compared to 2012 (down 18.9%).
Syndial increased the quantity of groundwater treated through TAF and used subsequently in its own production cycles (up 45.9% compared to 2012).
Eni is committed to integrating management of biodiversity and ecosystem services in all its operational enterprises throughout the project life cycle, in particular in the upstream sector. In order to achieve the goal of defining integrated action plans for biodiversity and ecosystem services in 20% of the Assessment Units exposed to biodiversity risk in 2012, specific Biodiversity Risk Assessment and Action Plans will be implemented to identify, assess and mitigate the potential impacts associated with E&P activities in any operating environment. Currently, the sites involved are DIME (Val d’Agri), Agip Oil Ecuador (Villano), KPO (Karachaganak), Eni Congo (M’Boundi), Eni Pakistan (Bhit and Badhra) and Eni US Operating Company (Nikaitchuq). The new exploratory and development projects will continue to ensure the proper integration of the issues of biodiversity and ecosystem services in pre-ESHIA.
Internationally, Eni’s commitment will continue in WBCSD, BSR, IPIECA and OGP with the chairmanship of the Biodiversity Working Group (BESWG). Moreover, membership of the Proteus partnership was renewed; this is an initiative promoted by UNEP-WCMC with the private sector that provides access to both the World Database on Protected Areas (WDPA) and the Integrated Biodiversity Assessment Tool (IBAT).
