– Thick-walled tubulars- Provide weight on bit (WOB)- Machined from solid alloy steel- Spiral-grooved or slick finish- API/ISO certified
– Drilling operations- Directional drilling- Stabilizing drill strings- Reducing vibrations
Kriloha Ltd. offers Drill Collars, heavy tubulars designed to provide weight on bit (WOB) and improve drill string stability. By adding stiffness and mass near the bit, drill collars ensure better hole quality, reduced vibration, and improved penetration rates. Manufactured from solid alloy steel forgings, Kriloha drill collars are available in slick finish or spiral grooved designs. Spiral grooves help reduce differential sticking and improve mud circulation in the annulus. Applications include vertical and directional drilling, stabilizing bottom hole assemblies (BHAs), and enhancing drilling efficiency. Each drill collar undergoes hardness testing, ultrasonic flaw detection, magnetic particle inspection, and dimensional verification, ensuring compliance with API 7-1 standards. As a supplier and facilitator, Kriloha Ltd. provides custom collar lengths, spiral groove designs, and full engineering support, making our drill collars the preferred choice for efficient and reliable drilling operations.
