Drilling Jars
HY-POWR Jars
HY-POWR jars are designed and manufactured for the severe drilling conditions encountered in vertical, directional and horizontal wells. This jar operates as a double-acting hydraulic jar. BHA recovery and reliable jarring operation is assured with this double-acting hydraulic jars delivering a high impact force when required regardless of position of BHA in vertical, deviated or horizontal wells. HY-POWR jars operates using the hydraulic metering delay system for both up-jarring and down-jarring. The magnitude of impact delivered by hydraulic jar is dependent on the magnitude of overpull or slackoff placed on the drillstring provided the maximum jar setting load is not exceeded.
UltraForce Jars
These new generation jars are designed and manufactured for the severe drilling conditions encountered in vertical, directional and horizontal wells. The UltraForce operates as hydro-
mechanical or double-acting hydraulic jar. BHA recovery and reliable jarring operation is assured with the UltraForce jars delivering high impact force when required regardless of position of BHA in vertical, deviated or horizontal wells. When operating as a hydro-mechanical jar, it functions with the combination of a hydraulic delay and mechanical latch.
UltraForce jars can be used as hydraulic up and down, mechanical up and down or hydraulic up and mechanical downdepending on customer application. UltraForce jars performs hydraulic jarring functions with the hydraulic metering valve system for both up-jarring and down-jarring. The magnitude of impact delivered by hydraulic jar is dependent on the magnitude of overpull or slackoff placed on the drillstring provided the maximum jar setting load is not exceeded. UltraForce jars performs mechanical functions using the latch/lock mechanis which trips down at a pre-selected compressional force and up at a pre-selected tensile force torque.
Safety Clamp
JA’s drilling jars are delivered to the rig in the open position with safety clamp placed around the exposed chrome area. The safety clamp keeps the jar extended while tripping and transporting. Caution: the safety clamp must be removed on the rig floor before the jar is run in the hole; failure to do so could result in damage to the jar and/or rig. There is also a possibility of down hole damages up to and including fishing operations.
