We manage oil spills in order to ensure the protection of the environment and actively participate in international prevention initiatives
The number of oil spills fell significantly in 2017, both in terms of operational spills and spills from sabotage. However, the volume of operational spills (3,228 barrels) has increased since 2016 due to the leak in a storage tank in the Val d’Agri Oil Centre occurred at the beginning of February. As of today, almost the total volume spilled on the site has been recovered. In 2017, the number of barrels spilled in operational oil spills (more than 90% referable to the E&P sector) has increased compared with 2016, mainly due to losses from a crude oil storage tank in the Centro Olio Val d’Agri identified at the start of February. By the end of 2017 more than 2,400 barrels of oil had been recovered, almost the total volume of the spill from the tank. As a consequence of this event, the E&P rate of operational/production oil spill increased significantly to 3.04 barrels/million barrels. In 2017, there was a reduction in the number of incidents by sabotage (-35% compared to 2016) and volume spilled (-31% compared to 2016); spills over a barrel are exclusively related to upstream activities in Nigeria, where, thanks to the commitment deployed to deal with these events, an 18% decrease was recorded in barrels spilled and a 29% decrease in events (for more info visit NAOC Sustainability website). The barrels spilled as a result of the chemical spill in 2017 are attributed to the E&P activity in Norway. To be highlighted the positive break between 2015 and the following years, which marks the positive convergence of all Eni efforts on all possible actions (see the following paragraph).
In recent years there has been a reduction in the volume of spills, in particular in the Exploration & Production sector.
The Eni strategy aimed at reducing operational oil spills and oil theft has been outlined through an increasingly joint action on all the possible intervention plans, from the administrative to the technical prevention aspects, control and quality / speed of intervention, also through participation in several international initiatives.
It deserves to be mentioned the project e-VPMS (Eni Vibroacous Pipeline Monitoring System), started as a research project and it became a patented product to be tested. It has been adopted in the Nigerian context (35 Km installed on the Ogbainbiri-Tebidaba line) and it will be further developed (eVPMS-TIP project) in order to detect vibrations from ground excavation and to anticipate the intervention before a potential break of the pipeline. In Nigeria, the decisive factors of the positive trend (end of 2015) were the following:
|Operational oil spills|
|Total number of oil spills (> 1 barrel)||(number)||83||85||55|
|- of which E&P||59||76||50|
|Volume of oil spills (> 1 barile)||(barrels)||1,634||1,231||3,228|
|- of which E&P||1,117||1,097||3,022|
|Operational oil spills/ 100% operated hydrocarbon gross productions (E&P)||(barrels/ million barrels)||1.3||1.2||3.0|
|Oil spills due to sabotage (including theft)|
|Number of oil spills (> 1 barrel)||(number)||167||158||102|
|- of which E&P||158||143||102|

|- of which current costs||8.75||15.67||27.64|
|- of which investments||30.70||21.40||25.72|
(a)In line with international standards all the values above refer to events involving more than 1 barrel. The data referring to sabotage includes oil spills due to attempted oil theft and vandalism.
(b) The value is included in the environmental expenditures and investments set out in the “HSE Management System Certification and Expenses” table.
