Bi-Directional Jar and Accelerators
The Reservoir Group Well Intervention Bi-Directional Hydraulic Jar & Accelerator’s primary function is to free stuck equipment in the well bore, and can be ran on Coiled Tubing or Jointed Pipe.

Running the Accelerator in Conjunction with the Bi-Directional Jar Amplifies the Jarring Force Being Applied Downhole.

The Accelerator is designed to achieve maximum stroke length, so maximum impact force is delivered, even if the weight applied is limited. The Bi-Directional Hydraulic Jar has benefited from comprehensive testing, resulting in a number of new features as standard. The hydraulic time delay system is compensated for load, temperature and pressure to ensure full jar action in highly deviated wells with high pressures/ temperatures.
