HI,
One of our wells is completed with a 3.5" tubing across 2 zones. The shallow one is a high pressure gas zone & the deeper one is oil. The gas zone is accessible through a 2.725" SSD & it is isolated by installing packers above and below it.
Offlate, the GOR of the well increased suddenly. Upon investigation it was confirmed that the tubing across the gas interval was leaking.
As the leaking interval is below the 2.725" SSD. We are looking for a patch system which can go through the 2.725" SSD & set across the tubing with 2.992" ID.
Kindly put forward your views.
