The patented Time Delay Gas Lift (TDGL) ™ system from Shale Oil Tools provides isolates your gas lift valves during installation and initial flow back.  The TDGL™ is compatible with all standard gas lift valves, protecting them with a barrier that dissolves after a predetermined period, ensuring that gas lift capabilities exist when required.

The TDGL™ is ideal for high pressure applications where backside isolation is required and is a superior alternative to disk subs that require a slickline intervention and produce debris that damages your gas lift equipment.   The TDGL™ is also perfect for ‘hybrid’ gas lift applications, enabling you to confidently convert from annular to tubular flow without tubing swap.  In this scenario, the  TDGL™ protects your tubular flow valves from damage that frequently occurs during annular flowback period - ensuring maximum gas injection and production of the tubular flow stage.

• Adaptable to gas lift mandrels of sizes from all gas lift providers and
• For convenience, the TDGL™ system can be assembled by your gas lift provider, Shale Oil Tools or in-house
• Configurable delay periods via metallurgies customized for unique annular fluid environments and temperatures
• No surface action required to enable injection

• Eliminates rig costs, lost production time and emissions related to future tubing swap and gas lift installation
• Safely circulate kill fluid if needed during installation without damaging gas lift valve seats
• Improve injectability and production while switching from annular to tubular flow in ‘hybrid’ gas lift applications
• Provides well control while installing gas lift valves
