Abstract
Examples described herein include systems and methods associated with a mechanical service tool. In one example, the service tool includes a power jar, an accelerator, and a linear actuator. The accelerator can be coupled to the power jar and provide assistance to the power jar. The linear actuator can be coupled to the accelerator and configured such to pull the accelerator spring within the accelerator with a force sufficient to fire the power jar. When the power jar is in a released state, the linear actuator can also be used to push or pull the entire accelerator and power jar assembly, which in turn can push or pull the target object within the wellbore. The linear actuator can also be used to move the power jar from a released state to a set state.
