Drill Collar

-Purpose: The essential function of our Drill Collar is to impart significant weight to the drill bit, ensuring it remains in constant contact with the geological formation. This critical component also enhances the stability of the entire drill string, optimizing performance and efficiency in drilling operations.

-Specifications:
1) Size: Available in a versatile range of outer diameters from 3-1/8" to 11", paired with standard lengths of 31 feet, ensuring adaptability to various drilling requirements.
2) Material: Crafted from high-strength alloy steel, our Drill Collars are designed to withstand the rigors of demanding drilling environments, offering exceptional yield strength and durability.
3) Weight: Heftier than typical drill pipes, our Drill Collar boasts a specific gravity of approximately 7.8, providing the necessary heft to facilitate efficient drilling processes.
4) Thread Connections: Engineered with precision, the thread connections are available in API Regular or other premium configurations, catering to diverse operational needs.

-Features:
1) Spiral grooves meticulously designed to mitigate the risk of differential sticking, facilitating smoother drilling operations.
2) Non-magnetic drill collars, expertly crafted to accommodate sensitive directional tools, ensuring unparalleled accuracy in directional drilling applications.
