Problem

To restart production of the existing low pressure Wells L2-FA that have been shut in for 2 years due to too high backpressure on the Nogat pipeline.

Solution

A patented Transvac Universal design Gas Ejector was installed, utilising high pressure gas from a new HP Well (from the L2-FB reservoir) to power the Ejector to draw-in and restart the L2-FA wells and thereby boost production. The Ejector was rated for 630 barg design pressure.

This Ejector recovered $127,000 per day
from shut in gas wells!

• Extra 0.9 MMscmd of gas produced from shut-in L2-FA wells
  
  
• New Ejector internals fitted as well pressures decline to maximise production. New internals have been fitted in less than one shift.
  
  
• Recent new Ejector internals increased production of L02FA-104 well by 0.5 MMscmd.
  
  
• Ejector has no running costs as it utilises motive gas energy normally wasted across a choke valve.

• Ejector requires no maintenance.
  
  
• Ejector produces no emissions to atmosphere.
  
  
• Universal Ejector design allowed manufacture of Ejector internals to be delayed until new HP well was drilled, thereby reducing project risk.
