Innovative developments for more efficient drilling


The all-purpose RJ2-2HM jars combine mechanical and hydraulic features.

  • The hydraulic section functions both during the strain and compression of the jar.
  • The mechanical section rules out unintentional firing during drilling or tripping.
  • The jar can be installed at any place in the drill string, both above and below the neutral point.
  • The main feature of this design is jarring against a stuck point with a variable pull/push and magnitude of impact in either direction.
  • Recommended for use in highly deviated holes with a high friction coefficient where it is problematic to generate a load sufficient to reset the jar.

Работа в скважинах со сложным профилем

Ensure excellent performance in highly deviated holes and at a high friction coefficient.

Возможность эксплуатации при температуре 200 °C

Can be used at 200°C when fitted with high-temperature seals
