When Jereh people are maintaining frac pump units in Henan oilfield, this oilfield invited them to help overhaul her IDECO 40T Workover Rig. Jereh engineers dismantled this rig, overhauling the engine, transmission and fluid & air systems, changing the gauges and instruments, valves, maintaining the chassis.
Jereh people feel confident that all the tasks will be accomplished triumphantly because Jereh people have the adequate experiences and theoretical knowledge.
