La fracturation hydraulique, également connue sous le nom de fracturation ou de fracking, est une technique utilisée dans l'industrie pétrolière et gazière pour améliorer la production de formations étanches à faible perméabilité. Elle implique l'injection d'un mélange à haute pression d'eau, de sable et de produits chimiques dans la formation rocheuse ciblée, créant des fractures qui augmentent le flux d'hydrocarbures vers le puits.

Conclusion :
La fracturation hydraulique a révolutionné l'industrie pétrolière et gazière, permettant la production de vastes quantités de ressources auparavant inaccessibles. Cependant, il est crucial de gérer les impacts environnementaux associés à cette technologie, en assurant des pratiques de développement responsables et durables. La recherche et les progrès continus dans les techniques de fracturation, y compris l'utilisation de proppants alternatifs et la minimisation de l'utilisation de produits chimiques, sont essentiels pour atténuer les préoccupations environnementales et maximiser les avantages de cette technologie.
