Title (EN) WATER TREATMENT SCHEMES FOR INJECTION WATER FLOODING RECOVERY PROCESSES IN CARBONATE RESERVOIRS
(FR) SCHÉMAS DE TRAITEMENT DE L'EAU POUR PROCESSUS DE RÉCUPÉRATION PAR INJECTION D'EAU DANS DES RÉSERVOIRS CARBONATÉS
Abstract:
(EN) Disclosed are water treatment apparatus and processes for the generation of injection water from seawater and produced water. The first water treatment apparatus includes a reverse osmosis (RO) unit that treats the seawater, a pretreatment unit that pretreats the produced water, and a carrier gas extraction (CGE) unit or dynamic vapor recompression (DyVaR) that treats the pretreated produced water and generates fresh water. The fresh water and the RO permeate are mixed with a portion of the seawater to generate the injection water. A second water treatment apparatus includes a reverse osmosis (RO) unit and a nanofiltration (NF) that treats the seawater in parallel, a pretreatment unit that pretreats the produced water, and a CGE unit or DyVaR unit that treats the pretreated produced water and generates fresh water. The fresh water and the RO permeate are mixed with the NF reject to generate injection water.
(FR) Cette invention concerne un appareil de traitement de l'eau et des procédés pour la génération d'eau d'injection à partir de l'eau de mer et de l'eau produite. Le premier appareil de traitement d'eau comprend une unité d'osmose inverse (RO) qui traite l'eau de mer, une unité de prétraitement qui prétraite l'eau produite, et une unité d'extraction de gaz porteur (CGE) ou une unité de recompression dynamique de vapeur (DyVaR) qui traite l'eau produite prétraitée et génère de l'eau douce. L'eau douce et le perméat d'osmose inverse sont mélangés avec une partie de l'eau de mer pour générer l'eau d'injection. Un second appareil de traitement de l'eau comprend une unité d'osmose inverse (RO) et une unité de nanofiltration (NF) qui traite l'eau de mer en parallèle, une unité de prétraitement qui prétraite l'eau produite, et une unité unité d'extraction de gaz porteur ou une unité de recompression dynamique de vapeur qui traite l'eau produite prétraitée et génère de l'eau douce. L'eau douce et le perméat d'osmose inverse sont mélangés avec le rétentat de l'unité de nanofiltration pour générer de l'eau d'injection.
