Field education. Apply the exact tool manual, current service sheet and approved well program for the serial numbered assembly. This course teaches understanding and preparation. It does not supply operating loads, timing or a universal firing sequence.

INTERACTIVE CONCEPT LAB

LAB

Where the
impact begins.

Follow an abstract energy sequence. The animation explains a principle. It does not depict a specific jar, direction selection or field operating procedure.

STAGE 01

Load stores energy in the system.

The workstring and any approved accelerator can store elastic energy as the planned axial load develops. The jar controls when the moving components can accelerate.

Hydraulic, mechanical and hybrid designs release and reset differently. Verify the exact model, configuration, pump conditions and vendor instructions before operating.
