OTC to Honor Caledyne with International Engineering Award

Caledyne, a leading energy industry engineering services and products specialist, will be recognized in May with a global award for its retrievable metal-to-metal (MTM) downhole seal system.

The company has been named the improved oil recovery (IOR) category winner of Hart's E&P Magazine's Meritorious Award for Engineering Excellence.

Each entry is assessed for: innovation in concept; suitability as a practical solution to a real oilfield problem; potential for improving efficiency or safety and capability for increasing profitability. The winners will be recognized during the opening day of the Offshore Technology Conference in Houston on May 4.

Following the launch of Caledyne's MTM seal system in 2007, the technology has been granted a European patent.

Developed at the company's base in Aberdeen, Scotland, the MTM downhole seal consists of flexible material contained inside a metal shell. The structure creates a complete metal barrier in the well, and when fully energized, protects it from the harshest downhole conditions. The system acts in a similar way to a standard rubber or elastomeric seal, while remaining resistant to high hydrogen sulphide (H2S) and carbon dioxide (CO2) concentrations.

Performance-rated to above 10,000psi differential pressure at 300 degrees C, the MTM seal can be installed on permanent and retrievable packers, bridge plugs, hanger packers, sliding sleeves and subsea sealing applications such as plugs and flange seals. Certified to ISO14310, the international standard for downhole equipment in the oil and gas industry, it will potentially supersede all elastomeric packing element systems currently on the market as temperature limitations and chemical compatibility concerns are no longer an issue.
Since its launch the MTM seal has completed a number of installations in various sizes around the world.

Roland van Dort, Caledyne managing director, said, "This award is significant recognition for technology we have developed here in the north-east of Scotland and recognizes just how important the metal-to-metal seal is for the industry.

"As opposed to traditional seals, the MTM seal enables operators to confidently develop reservoirs that previously were impossible due to elastomeric limitations. Because one seal is suitable for any downhole condition, irrespective of temperature, pressure, corrosive environment and chemicals injected, stock levels are vastly reduced. This has a knock-on cost effect."
