Technical specifications

Prevents the back flow of the cement slurry or the drilling mud from the annulus in to the tubing space of the liner during RIH and isolates the inside tubular space of the liner for the case of oil, gas and water shows.

CIRCULATION VALVES

Technical specifications

Provides fluid circulation and is designed to activate the cementing sleeve.

Installed in the casing string during well cementing operations, or positioned in the liner assembly below the cementing sleeve.

Circulation ports are opened hydraulically; closure is achieved by dropping and seating a ball.

Once the ball is seated and locked in place, the valve seals off completely, preventing cement slurry from entering the lower section of the casing string or liner.
