Unconventional Gas Lift: Below Packer Systems

Flowco’s Below Packer Gas Lift systems deliver lift at the true point of need deep in the wellbore, beyond the limits of conventional gas lift. By lowering bottomhole pressure and reducing fluid fallback, these systems maximize production in unconventional and low-pressure wells.

What is Below Packer Gas Lift?

Below Packer Gas Lift (BPGL) extends gas injection past the conventional lift point, delivering gas into deeper sections of the wellbore such as the curve, toe, or long perforated intervals. By reducing hydrostatic pressure where it matters most, BPGL unlocks production that standard gas lift systems cannot access.
Enables deeper injection for lower flowing bottom-hole pressure
Maximizes production in horizontals and toe-up laterals
Protects upper gas lift valves from fluid and debris exposure
Allows easy chemical treatment of tubing and casing
Provides efficient solutions for both horizontal and vertical wells

How It Works

Understanding Below Packer Gas Lift

Conventional gas lift injects above the packer, which is effective but often not deep enough for many unconventional wells. Flowco’s Below Packer systems extend injection further downhole, reducing hydrostatic pressure and minimizing fluid fallback. The result is more consistent unloading, lower injection volumes, and improved well performance.

Types of Below Packer Gas Lift Systems

Packer Bypass System (PBS)
Micro-Annulus Crossover System
Increased Annular Velocity (IAV) System
Combines a conventional gas lift setup with a bypass assembly that routes gas through the packer. This allows lift at the end of the tail pipe in the curve where gradient is lowest.
  • Delivers lift at the lowest flowing pressure point
  • Provides chemical treatment access during unloading
  • Prevents re-entry of fluids during shut-in

Uses a crossover adapter and internal injection string to achieve deeper injection, either in toe-up horizontals or vertical wells with low reservoir pressure.
  • Lowers flowing bottom-hole pressure more effectively than conventional lift
  • Isolates injection pressure from perforations
  • Improves gas utilization and fluid density reduction

Employs optimized tubing and injection string sizes to maintain critical unloading velocity. Available in horizontal and vertical configurations for wells requiring pressure isolation.
  • Maintains velocity to prevent liquid loading
  • Reduces hydrostatic pressure on the formation
  • Simple installation without wellhead modification
