Gas Lift Challenges

Little has changed over the past decades to prepare the industry for the gas lift challenges being faced today. These include:

  • Deeper, longer, and more highly deviated wells.
  • Higher pressures / temperatures and more corrosive / scaly environments
  • Increased focus on well integrity
  • Increased recognition of production inefficiencies due to multipointing
  • The need to retrofit new or upgrade existing gas lift systems without recompletion
  • The need to reduce the number of well interventions

To address these challenges, PTC has developed the next generation of gas lift technologies, which are now widely used by most OPCOs worldwide.


The increased reliability, flexibility and longevity these technologies offer, has also led to the development of a unique life of field approach to gas lift system design.


Gas Lift Valve Technology

The Gas Lift Valve (GLV) has historically been the component most prone to malfunction and failure in a gas lift system. Scale, erosion, chattering, and unloading valve bellows fatigue or dome charge valve leakage, are widely reported causes.


PTC has designed, qualified and incorporated many revolutionary features in our Lift-family GLVs that have greatly improved reliability and operational efficiency. These include:

  • Proprietary barrier certified orifice and back-check valve system, which is less prone to chattering, and erosive wear of the metal to metal sealing surfaces
  • Unique low load rate / long stem travel dual operating bellows type Injection Pressure Operated (IPO) valves. These valves can be reliably used as operating valves, eliminating the need for interventions to change lift gas injection depth. The bellows are rated to 12 500 psi and have been tested to 50 000 full open/close cycles.
  • Shear activated GLVs that allow operators to run multiple valves (unloading and orifice) in the same completion string and shear them open in one operation.
    Anti-scale valve design providing longevity in scaly environments.


GoLiftTM Retrofit Gas Lift Straddles

PTC’s GoLiftTM through tubing gas lift straddle system offers a cost-effective alternative to workovers where there is a need to retrofit new or upgrade existing gas lift or chemical injection systems, without compromising well integrity.


Life of Field Gas Lift Design

Traditionally decisions regarding the optimum number and setting depths of valves in gas lifted wells have been made considering only a small number of operating scenarios. As a result, wells often do not perform as expected.


PTC’s unique life of field design process considers a wider range of life-cycle operating conditions and data uncertainties. It therefore provides a more robust design to ensure maximum production, and reliability over the life of the well.
