Title
(EN) ADVANCED TREATMENT FOR PRODUCED WATER
(FR) TRAITEMENT AVANCE DE L'EAU PRODUITE
Abstract
(EN)
Produced water, the aqueous fraction of the produced fluids generated by an oil or gas well poses a significant water treatment and disposal problem. The instant invention discloses methods and apparatus for the advanced treatment, particularly biological treatment, of produced water in an off-shore facility in order to reduce the amount of pollutants discharged with the produced water and to avoid the cost and other disadvantages of deep well injection disposal of produced water. Offshore biological treatment is disclosed in vessels designed for deployment on the sea floor, in the water collumn, and at the sea surface.
(FR)
L'eau produite, à savoir la fraction aqueuse des fluides produits générés par un puits de pétrole ou de gaz, pose un grave problème dans les domaines du traitement des eaux et de l'élimination des déchets. L'invention concerne des procédés et un appareil permettant d'effectuer un traitement avancé, notamment biologique, de l'eau produite dans une installation offshore; elle vise à réduire la quantité des polluants s'échappant avec l'eau produite, et ce afin d'éviter les coûts élevés et autres inconvénients de l'élimination de l'eau produite par l'injection de ladite eau dans des puits profonds. L'invention concerne aussi un traitement biologique offshore effectué dans des récipients conçus pour être déployées sur fond marin, dans des colonnes d'eau et à la surface de la mer.
