HYMEC HFJ FISHING JAR & ENERGIZERThe HFJ Fishing Jar & Energizer are a new generation of tool designed and manufactured for the severe �shing operations of today, requiring secure and durable operation and providing high impact as and when required regardless if in vertical, high angle or the horizontal section of the well.
Jarring UpTo jar up, apply overpull at the jar as required and wait for jar to �re. The more overpull applied on the jar, the greater the impact will be achieved. To repeat jarring, reset the jar by applying weight down on the jar to return the jar to it’s pre jarring position ready to be jarred up again as required.
Bumping DownUsing the weight above the jar to bump down from the jar being in it’s fully extended position. Dropping the weight down will give bump action down and can be repeated after extending the jar again. To increase possible bump, pull up to stretch the string before release to bump down. The greater the pull up before release, will increase the bump down force.
Energizer Up OperationThe energizer will automatically be applied when overpull is applied to the jar so fully concentrate on the loads applied on the jar and the energizer will adjust as required.
The energizer will, when operated with the ‘HFJ’ Jar, increase acceleration of hammer weight between jar and energizer and thereby increase impacts.

PUMP OPEN FORCE JAR AND ENERGIZERPump pressure will generate a force, which wil try to open the tool and thereby increase impact. For calculations please refer to Pump Force table.
In horizontal wells the energizer will, due to the Pump Open Force and spring force, also assist in moving the BHA to maintain weight on bit if used while drilling.
HFJ Jar & Energizer notesThe HFJ Fishing Jar & Energizer are manufactured using the latest technology and materials. The tools are designed to allow torque applied to jar while �ring. The durable hydraulic system provides the jar with high and consistent impacts, even in horizontal wellbore placements.
The HFJ Fishing Jar are of robust design and can be relied upon in the most severe �shing applications. With the full involute spline drive arrangement, they can also be used in drilling applications. If used for drilling, correct placement is to be ensured for problem free operation.
