SafeLift Orifice Gas Lift Valve

PTC’s SafeLift® Gas Lift Valve is the only valve accredited to the most extreme barrier and erosion testing requirements. SafeLift®’s unique erosion and chatter resistant check valve design, provides enhanced well integrity and well up-time. Since its introduction in 2007, the product family has achieved significant market penetration with all major Operating Companies.

 

Challenge

Change out of gas lift valves (GLV) due to valve failures or non-optimum gas lift design can be costly, especially in offshore and subsea environments.

 

Interruption of, or non-optimum gas lifted production has a negative impact on field economics. Furthermore, leaking GLV’s often lead to downgrading of the wells integrity level.

 

Solution

Petroleum Technology Company´s (PTC) SafeLift® valves have a proprietary orifice and back-check system, which eliminates chatter and wear. This design has proven to have unsurpassed longevity and reliability, which reduces intervention costs. In addition to the valve geometry, PTC offers a unique life of field (LOF) gas lift design process, which ensures optimum design for all phases of the well.
