  • Monolithic blade stabiliser tool for drill string
    Patent number: 10415325
    Abstract: A drilling string stabilizer tool comprises a cylindrical body and a plurality of stabilizer blades machined as an integral component forming in this way a monolithic blade stabilizer tool. The stabilizer blades have an elongated shape and are aligned in the direction of the axis of the cylindrical body. The blades are disposed in such a way to result in an almost constant flow-by-area.
