OPERATING PROCEDURES
JARRING UPEach jar is sent to the field with a preset latch up value & delay time.Upwards pull force must be able to overcome the preset latch value plus the drill string weight above the jar plus any applicable hole drag.When this value is exceeded the mechanical latch releases and the hydraulic delay will engage. The hydraulic delay is adjustable from the service shop.At the end of the hydraulic delay, the jar will fire in an upwards motion.
RESET UP JARIf the jar fires too soon, it may not have been pushed down in the latch position.After the jar has fired, set the drill string down on the jar to close and latch.The jar should close at about 5,000-10,000 dekanewtons (calculation must takeinto account the drill string weight below the jar).Repeat the jarring up and reset up operations as required.
JARRING DOWNEach jar is sent from the factory with a preset latch down value.Apply weight on the jar that will exceed the preset latch down value (availablefrom the service shop). Take into account any dog legs or other factors that mayreduce the affect of the weight getting to the jar.The jar will fire downwards with no hydraulic delay.
RESET DOWN JARPicking up on the jar will pull it back into the latched position.Repeat the jarring down and reset down operations as required.
