UK-based EV, a specialist in downhole video technology, has launched its Optis HD Electric line camera to the well intervention market, which they say can provide vital wellbore imagery that can save time and reduce risk.
The new technology, which was three years in development, allows operators to stream color video, using the latest video technology combined with high-speed telemetry and video compression techniques. It has been designed for well integrity inspection and monitoring of downhole corrosion and mechanical damage and has successfully completed a wide run of 100 field trial jobs in Canada before becoming commercially released in the North Sea Gulf of Mexico, Saudi Arabia, and Australia.
The Optis Electric Line HD tool has a diameter of 1-11/16in. (43mm), length of 11.8ft (3.6m), pressure rating of 15,000 psi (1034 bar), and a maximum operating temperature of 257°F (125°C).
The color sideview camera has its own LED lights and a lens with a focal length from 1in. to 8in. providing excellent pictures in 2-3/8in. tubing and up to 21in.-diameter marine risers. Rotation of the sideview camera is controlled from the surface with a high side indicator to show where the camera is looking in deviated wells.
Francis Neill, EV Chief Executive, said: "The launch of our Optis HD Electric Line camera demonstrates a significant advancement in the application of wellbore camera technology, which we are delighted to bring to the global well intervention market.
"The technology has the capacity to stream color video at up to 25 frames per second, using the latest in high speed telemetry. The camera creates high quality pictures downhole, allowing our clients to diagnose issues, resolving them quickly and reducing future risk which could have been labour intensive and costly to correct if they weren't identified earlier."
"The new camera features improved speeds and picture quality compared to similar downhole video cameras currently on the market, allowing for advanced inspection of oilfield surface equipment for integrity issues."
EV, which splits its headquarters between Norwich and Aberdeen, has a team of around 90 employees, 13 of whom work in the Aberdeen office. The company has 17 global bases.
