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 are torqued and pull tested to assure proper working order.
A combination of a bumper jar, an oil jar and an energizer gives you the maximum strength and downhole jarring needed for hopefully freeing your fish. The bumper jar is run directly on top of the bottom hole assembly, which allows you to knock it down in order to release it. The oil jar runs 2nd in the work-string right above the bumper jar, allowing you to jar upward and downward. The energizer jar is usually run up the string at the top of your drill collars. This will help keep the jarring action as close to your fish as possible while preventing damages that may occur to the rig and its components.
