Analyse des risques et dispositif de suivi : Le cas d'Izaute et Lussagnet

Elf Aquitaine Production

Abstract

The natural gas storage in the drinkable aquifer of Lussagnet sands has raised a specific question: isn't there any risk to deteriorate this vital resource or to make it poorer?

In order to answer to this question. Elf, in accordance with the public authorities, has carried out studies and researchs aiming to assess the risks incurred, and implemented a permanent follow-up device to prevent them.

This article which is illustrated by a follow-up of the physicochemical quality of waters aims to show how a new approach, conciliating the gas storage and the preservation of the aquifer, could be developed.
