Dans le monde du pétrole et du gaz, l'expression "eau potable" peut sembler déplacée. Après tout, l'industrie est souvent associée aux pipelines, aux plateformes de forage et à l'extraction d'hydrocarbures. Cependant, l'eau potable, définie comme l'eau propre à la consommation humaine, joue un rôle étonnamment crucial dans ces opérations.
Voici comment l'eau potable est utilisée dans l'industrie pétrolière et gazière :
1. Eau potable pour le personnel : Cela semble évident, mais fournir de l'eau potable propre est essentiel pour la santé et la sécurité des travailleurs sur les sites pétroliers et gaziers éloignés.
2. Hygiène et assainissement : L'eau potable est essentielle pour maintenir des normes d'hygiène de base sur le site, y compris les installations de lavage des mains, les douches et les systèmes d'assainissement.
3. Extinction d'incendie : L'eau est un élément clé des systèmes d'extinction d'incendie, et l'eau potable peut être utilisée en cas d'urgence à cette fin.
4. Fluides de forage à base d'eau : Bien qu'elle ne soit pas toujours potable, l'eau est un élément crucial des fluides de forage, qui lubrifient les mèches de forage et éliminent les déblais du puits.
5. Additifs pour fluide de fracturation : La fracturation hydraulique, ou « fracking », utilise un mélange d'eau, de sable et de produits chimiques pour extraire le gaz naturel et le pétrole des formations de schiste. Bien que la plupart des fluides de fracturation ne soient pas potables, certains additifs peuvent être dérivés de sources d'eau potable.
6. Injections de vapeur : Cette méthode de récupération assistée du pétrole consiste à injecter de la vapeur dans les réservoirs de pétrole pour augmenter la production. Dans certains cas, l'eau potable peut être utilisée pour produire de la vapeur, en particulier dans les régions où l'accès à des sources alternatives est limité.
