The ShearLift-T
PTC’s ShearLift-TTM are the only Gas Lift Valves that allow multiple IPOs and orifice GL valves to be simultaneously sheared open using tubing pressure. ShearLift-T’s unique design eliminates the need to run dummy valves, thus saving significant time during well completion or commissioning. To date, an average of two days rig time has been saved per well.
Application
When completing new gas lift wells the standard practice is often to install dummy valves in all side pocket mandrels. These dummy valves provide a barrier between the annulus and the tubing during the well completion phase. Before the wells can start producing, the dummy valves need to be replaced with gas lift valves. These intervention operations are often time consuming and costly.
ShearLift-TTM valve has a unique design, which utilizes the barrier technology from the standard SafeLift®. The ShearLift-TTM valve provides a barrier between the tubing and annulus when installed in a side pocket mandrel.
The check valve is held in the closed position by a shear device located in the nose section of the valve. Increasing the tubing to annulus differential pressure, to a predetermined level, shears open all ShearLift-TTM (IPO & Orifice) valves in the tubing string. This allows communication from annulus to tubing. Costly change out of dummy valves in new completions can be avoided by using ShearLift-TTM.
Key Benefits
- Field proven design and operation
- Considerable time saving, as no wireline intervention required prior to production start up
- Best in class reliability and longevity ensures enhanced productivity and well integrity

Application Areas
Production Optimisation
Prevent water influx, increase oil and gas production and extend well lifespan. Isolate zones, retrofit gas lift and optimise revenue through tailored solutions.
Interventionless Completion Installations
Interwell enhances production and eliminates intervention needs during and after completion installations by providing remotely operated completion tools.
Rigless Installation of VXT
The Inter Remote Bypass Valve (IRBV) enhances efficiency in subsea operations with a vertical x-mas tree (VXT). It enables batch operations and reduces costs by minimising rig time and interventions, providing a remotely controlled, pressure-cycled barrier compliant with ISO standards.
