Title
(EN) INJECTION WATER PRE-TREATMENT AND INJECTION SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ D'INJECTION ET DE PRÉ-TRAITEMENT D'EAU D'INJECTION
Abstract
(EN)
A system and a method for groundwater pre-treatment and injection are disclosed. The pre-treatment and injection system comprises subsea water wells (1, 1') connectable to a water injection system (2) comprising a water injection pump (3) in flow communication with a water injection well (4), wherein the subsea water wells (1, 1') are made as a hole into a groundwater holding strata under the mud-line (ML) with a water permeable (9') or non-permeable (9) completion using the seafloor soil for filtration, with an inner tubing (12, 12') connectable to the seawater injection system (2) via a valve (5).
(FR)
La présente invention concerne un système et un procédé pour le pré-traitement et l'injection d'eaux souterraines. Le système de pré-traitement et d'injection comprend des puits d'eau sous-marins (1, 1') raccordables à un système d'injection d'eau (2) qui comprend une pompe d'injection d'eau (3) en communication fluidique avec un puits d'injection d'eau (4), les puits d'eau sous-marins (1, 1') se présentant sous la forme d'un trou dans des strates de rétention d'eau souterraine sous la ligne de boue (ML) avec une complétion perméable à l'eau (9') ou non perméable à l'eau (9) en utilisant le sol du fond marin pour la filtration, avec un tube interne (12, 12') raccordable au système d'injection d'eau de mer (2) par l'intermédiaire d'une vanne (5).
