Eastern has a complete line of jars to accommodate your fishing tool equipment. These jars are essential in and during fishing tool operations. The jars, whether oil, bumper, or accelerator (Energizer), are torqued and pull tested to assure proper working order.
A combination of a bumper jar, an oil jar and a energizer gives you the maximum strength and downhole jarring needed for hopefully freeing your fish. The bumper jar is ran directly on top of the bottom hole assembly which allows you to knock down in order to release. The oil jar is ran 2nd in the work-string right above the bumper jar. This jar allows you to jar both upward and downward. The energizer jar is usually ran up the string, usually at the top of your drill collars. This will help in keeping the jarring action as close to your fish as possible while relieving undo damages that may occur to the rig and its components.
