Technology
MDS9 has unveiled our Ruger X RSS specialized motors, representing a substantial expansion of our product line. The Ruger X RSS motors signify a pioneering advancement within the drilling motor development sector. Within this line, we offer the Ruger X motor model, available in both oil lubricated and mud lubricated sealed versions, which excel in terms of torque, bearing load capacity, and extended component life exponentially to reduce cost. Additionally, we present the Ruger X HT model, featuring oil lubrication and sealing, with significantly enhanced torque capacity and zero fluid bypass. Finally, our Ruger X mud lubricated model, characterized by a short bit to bend (SBTB) length, possesses the capability to efficiently drill all three sections of a well in a single trip.
Both mud lubricated and oil lubricated Bearing Assemblies are complemented by a distinctive, vibration-free transmission system, ensuring optimal performance, reliability, efficiency, and extended operational lifespan of our tools. MDS9 Ruger X Motors are designed to maintain a consistent RPM and torque at the bit, thereby ensuring a constant rate of penetration (ROP) and extending the lifespan of both the motor and the drill bit. Our proprietary bearings are engineered to withstand prolonged radial and thrust loads, whether during bottom hole drilling or back reaming operations.
MDS offers Drilling Motors with surface-set adjustable 0-3 degree Bent Housing Assembly or Fixed Bent Housings, all equipped with Rotor Catch Assemblies. Furthermore, our assortment includes near-bit stabilizers and offset kick pads, available upon request. Our motors are conceived with a primary emphasis on reliability and simplicity, delivering exceptional performance in the field and facilitating effortless servicing. All components adhere to Aerospace AS9100D or ISO9001 rigorous quality standards and are crafted from premium materials and coatings, meeting the diverse requirements of various drilling applications.
