Subsurface Flow Controls
Halliburton subsurface flow control systems are designed to simplify completion programs and maintain production control for the life of the well.


DuraSleeve® Sliding Side-Door® Sleeve
The DuraSleeve® Sliding Side-Door® circulating and production sleeve is a full opening device that can be operated using standard slickline methods. It incorporates an internal sleeve that when open enables communication between the tubing and tubing/casing annulus.

EquiFlow® Autonomous Inflow Control Device
Restricting water and gas production at breakthrough, this autonomous inflow control device (AICD) helps increase recoverable reserves, extend well production, and reduce the expense and risk of unwanted fluid production.

FS Fluid Loss Isolation Barrier Valve
The FS fluid loss isolation barrier valve provides a reliable, interventionless solution for fluid loss control in your completion eliminating potential formation damage.

LA Liquid Spring-Actuated Anvil® Plugging System
The LA liquid spring-actuatedAnvil® plugging system is a pressurecycle-operated device that allows theoperator to perform tubing tests or sethydraulically activated tools and thenhave full tubing bore ID withoutwireline or coiled tubing intervention.

LV4 Lubricator Valves
The LV4 lubricator valve is a high performance, surface-controlled tubing- retrievable isolation barrier valve that is used as part of a downhole lubricator system.

TTRD Protection Sleeve
The TTRD (Through-Tubing Rotary Drilling) protection sleeve is designed to protect downhole seal bores from damage as the drillpipe rotates within the tubing during a TTRD operation.
