HYDRAULIC
MECHANICAL JARS
RJ-2HM
HYDROMECHANICAL JARS COMBINE FEATURES OF BOTH MECHANICAL AND HYDRAULIC JARS; SUCH JARS ARE RECOMMENDED FOR VERTICAL AND DIRECTIONAL (THREE-SECTION) WELLS.
MAIN BENEFITS:
- THE MECHANICAL LATCH PREVENTS UNCONTROLLED JARRING DURING DRILLING OR TRIPS.
- THE UPWARD IMPACT FORCE CAN BE ADJUSTED BY APPLYING AN ADDITIONAL PULL TO THE JAR DURING THE HYDRAULIC DELAY.
- THE JAR CAN BE RUN DURING DRILLING AT THE BOTTOMHOLE TEMPERATURE UP TO 200°C (WITH HIGH TEMPERATURE SEALS).

HYDRAULIC
MECHANICAL JARS
RJ2-2HM
THE RJ2-2HM JARS ARE ALL PURPOSE AS THEY COMBINE MECHANICAL AND HYDRAULIC FEATURES.
MAIN BENEFITS:
- THE HYDRAULIC SECTION WITH A METERING VALVE IS ISOLATED FROM THE DRILLING MUD WITH SEALS IN THE MECHANICAL AND SPLINED SECTIONS.
- THE MECHANICAL LATCH PREVENTS UNCONTROLLED JARRING DURING DRILLING OR TRIPS.
- THE MAGNITUDE OF THE JARRING FORCE, BOTH UPWARD AND DOWNWARD, CAN BE ADJUSTED BY APPLYING ADDITIONAL TENSION OR COMPRESSION LOAD DURING THE HYDRAULIC DELAY.
