JetRotor™

Detailed Description

The JetRotor™ tool operates at the highest power and pressure levels available in the industry. The patented open-flow seal design virtually eliminates power losses due to leakage and friction. This seal design ensures that maximum hydraulic power is delivered to the jets.

High-pressure rotary jetting offers the ability to remove mineral scale safely and quickly and to stimulate well completions with no risk of damage to production tubing or downhole equipment.  Tempress JetRotor™ tools are compatible with a broad range of fluids including acid, making them applicable in almost all coiled tubing well service jobs. The design is highly compact, which greatly simplifies transport, BHA setup and job execution.
