Gas Breakthrough Wells | Proper Shut-off Solution

Challenge: wells are producing high GOR from day one ranging from 1000 to 2000 m3/m3 and other wells suffer from gas breakthrough after some time of producing the wells. 

These wells can be GL wells with high formation gas from the reservoir or self-flow wells with high GOR.

key requirements: 

1.     Technical info and specs about the technology that can control high GOR wells and produce at economic rates. 
2.    Recent case histories preferably in in middle east and GCC if any.
3.    How this technology will add value.
4.    Indicative cost of the technology if available and can be indicated at this stage.
