The Neyrfor TTT thru-tubing turbodrill provides the highest downhole mechanical power output by efficiently converting hydraulic energy into mechanical energy. Power can be tailored for the most demanding thru-tubing applications, delivering higher speed and lower torque.
The turbodrill is available in 2 1/8-in and 2 7/8-in ODs to accommodate a broad range of applications, including coiled tubing, milling, and acidizing operations.
The tool’s all-metal construction enables reliable operation in high temperatures where conventional motor life is shortened and elastomer stators may be unusable. Frequent tripouts to change motors are avoided because the turbodrill can stay in hole for extended periods in high-temperature, pressure-sensitive, and harsh-fluid environments. The turbodrill also works efficiently with dual-phase milling fluids.
The Neyrfor TTT turbodrill ensures a balanced and consistent milling profile capable of efficiently clearing cement and scale from tubing or liners. It also produces small, uniform cuttings for enhanced hole cleaning.
With its robust blade stages and thrust-bearing design, the Neyrfor TTT turbodrill produces less reactive milling torque compared with conventional positive displacement motors, protecting downhole tools and coiled tubing from extended torsional stress. Its concentric design ensures significantly less destructive vibration for the tool and the BHA.
Fit-for-purpose intervention mill coupled with a thru-tubing turbodrill milled for more than 100 h in temperatures up to 346 degF.
In a gas well where buildup had blocked access to a perforated interval, the operator successfully removed 206 ft of hard scale in the production liner.
