This video of the month comes from a recent operation for Neptune Energy, a leading offshore gas producer in the Netherlands, where EV’s Optis Technology was used to pin-point and isolate water entry in a conventional well.
The operator experienced increasingly high water production in their conventional gas well. With the well unable to cope with lifting this produced water, and with no clear indication of which zones the water was entering from, the operator had no choice but to shut-in the well. Upon reaching 4600m depth, the camera revealed severe scale build-up, in addition to the presence of water. As the camera continued to descend, the perforations producing water could easily be seen with flow increasing throughout the stage.
By confirming the presence and pinpointing the location of water entry, the operator was able to install a straddle isolation system over the water producing zone, thus eliminating the water at source and restoring profitable hydrocarbon production once again.
