ABSTRACT:
A system for completing water injection wells includes an injector well completion system. In an embodiment, an injector well completion system for liquid injection in a formation includes a casing string disposed in a wellbore having a tubing bore. The casing string includes a casing and a sliding sleeve. The sliding sleeve has a pressure control valve having open and closed positions, an actuator mandrel having a flow control device, and an injection pressure communication port. The open position of the pressure control valve actuates the actuator mandrel to align the flow control device and the injection pressure communication port to inject liquid from the tubing bore to the formation and generate fractures in the formation.
