ABERDEEN - EV Offshore Ltd., a provider of downhole, subsea and well intervention camera inspection services , has successfully completed a downhole inspection operation on behalf of CNR International (UK) Ltd. in the North Sea.
The inspection operation took place on CNR's Ninian South well located in the East Shetland Basin offshore Scotland. During recovery operations on the well, CNR encountered a problem indicating damaged casing. The company tapped EV Offshore to carry out visual inspections downhole in order to assess the situation.
EV Offshore mobilized a full inspection package, which consisted of the EVOLeye camera inspection system, drill-pipe running tool, centralizers, and a full complement of back-up equipment. EV Offshore states that EVOLeye offers full, continuous hemispherical viewing - in color or monochrome - while running downhole. It is also capable of flushing turbid water and dislodging obstructions at target depth to offer a clear view.
Video images from EVOLeye revealed significant corrosion damage to the casing strings in a very limited area at sea level. By running a casing spear on drillpipe, while simultaneously operating the EVOLeye on tugger line to supply real-time images, CNR was able to manipulate the casing spear into the damaged casing and recover it.
"By using the EVOLeye to assess the problem, we were able to recover the well, retrieve the damaged casing and re-complete the well," said Chris Wark, senior drilling engineer for CNR. "There is no question that EV Offshore is directly responsible for making that possible".
