Title (EN) CONTROLLED RELEASE BIOCIDES IN OILFIELD APPLICATIONS
(FR) BIOCIDES À LIBÉRATION PROLONGÉE DANS APPLICATIONS DE CHAMP DE PÉTROLE
Abstract: front page image
(EN) Described is a method for treating a subterranean formation penetrated by a wellbore, the method including the introduction of a well treatment fluid containing at least an encapsulated biocide. Once the encapsulated biocide is introduced and after a predetermined period of time, a biocide is released from an encapsulation material and treats the wellbore and the subterranean formation.
(FR) L'invention concerne un procédé de traitement d'une formation souterraine pénétrée par un puits de forage, le procédé comprenant l'introduction d'un liquide de traitement de puits contenant au moins un biocide encapsulé. Une fois que le biocide encapsulé est introduit et, après une période prédéterminée de temps, un biocide est libéré d'une matière d'encapsulation et traite le puits de forage et la formation souterraine.
