– Shifting sleeves- Activating downhole tools- Delivering impact force- Fishing assistance
At Kriloha Ltd., we supply Go-Devils, free-falling impact tools used to deliver a downward mechanical force inside the wellbore. Designed as a simple yet effective solution, the go-devil is dropped into the well to strike a target, such as a sliding sleeve, plug, or tool requiring activation. Constructed from forged alloy steels with high-density bodies, Kriloha go-devils are engineered to deliver reliable impact energy without deformation. Their rugged design and simplicity make them a staple in wireline and slickline operations. Applications include shifting sliding sleeves, activating mechanical tools, breaking shear pins, and assisting fishing operations by providing impact force. Each go-devil undergoes impact energy validation, weight calibration, and dimensional checks, ensuring safe and efficient performance. As a supplier and facilitator, Kriloha Ltd. offers custom go-devil weights, flat-bottom or cutter-type designs, and operator training, making our go-devils the preferred solution for reliable impact delivery in intervention jobs.
