This video of the month showcases how the application of FishVA, supported by Optis technology, helped Frisia Zout, a leading salt producer in the Netherlands, restore production from their salt cavern well.
The well produces high-quality vacuum salt, using a borehole brine process. Following a collapse of the cavern formations, the outer 11 ¾” casing was sheared, creating a fish that completely isolated the cavern, thereby preventing salt production. In response, the operator planned an intervention to remove the fish by cutting the affected casing sections, and dropping the fragments into the cavern.
With multiple cuts required, EV’s Optis R125 camera was deployed on Electric-line to provide real-time visual confirmation of success at each stage of the operation.
The camera was run downhole to the target depth, where the detailed real-time footage confirmed the 7 inch casing was successfully cut. The sideview footage revealed the cut in more detail, showing no anomalies. By applying proprietary Visual Analytics processes, a 360 degree continuous image was generated, providing a complete profile of the successful cut for clear and concise confirmation.
