WellFlo® – Deep Gas Lift System (DGL) - Modelling
Conclusion:
Based on well data, on gas lift this example well will produce 3,810 BFPD, where the gas injection is
set at the injection depth at 9,150 ft MD.
Deepening the gas injection depth to 11,043 ft MD results in a change in well deliverability and performance with an additional 489 BFPD with a net gain of 167 BOPD. at 66% water cut.

IGLS Case History – UK
The IGLS system was deployed in an efficient and professional manner a with no safety or technical issues raised during the installation and the operation.
Production up time was increased from 3 months per year to 12 months per year. – Cyclic Production - ROI ~ 27 Days
If platform ESD “trips” well can be taken back online immediately with no “down time”.
First deployment and Installation with the class 2 Dual Flow Safety Valve. (debris & sand tolerant)
Dual Flow Lock was designed, developed and run for the first time in the North Sea.
