The Logan Bi-Directional Coiled Tubing Jar is designed to hit upward and downward blows. It can be dressed to only hit up or down. These tools’ small outside diameters and shorter lengths make them ideal for milling, drilling, workover, remedial, or completion operations, especially in vertical, deviated, and ultra-deep wellbores. Independent hydraulic timers respond to any push or pull load. The Bi-Directional Coiled Tubing Jar operates by straight push or pull with splines that are always engaged.
