The Fishing Jar is used to deliver an upward impact blow to a stuck downhole component, release fishing tools or activate shearing mechanisms. The jar is designed to provide variable hitting loads and extended periods of continuous jarring in a wide range of drilling conditions.
The Bumper Sub is a heavy-duty joint that provides better control of the fishing string and reduces bottomhole assembly (BHA) vibration. Providing a more subdued upward or downward bump to the fishing string, the Bumper Sub also aids in disengaging a fish after retrieval.
