Gas Lift
Inside this lesson
- Explain how gas lift injects high-pressure gas into the tubing (down the annulus, through gas-lift valves in side-pocket mandrels) to aerate and lighten the fluid column
- Show that lightening the column cuts the hydrostatic head and so lowers the VLP curve, raising the operating rate
- Distinguish continuous gas lift (steady, deliverable wells) from intermittent gas lift (low-rate or weak wells)
- Explain the optimum gas-lift injection rate - too little gas under-lifts, too much adds friction and slip that eat into the gains
