An advanced jarring method was developed for deviated wells where conventional jarring is not possible. Comparing the results of jarring impact with this new method to jarring impact with conventional methods showed similar effectiveness. Rather than relying on gravity or energy stored in the cable (slickline or e-line), a high-performance, fully adjustable spring jar uses an accelerator to provide consistent energy storage and delivery during the jarring operation. However, this cannot be used in highly deviated wells because there may not be enough cable pull to energize the accelerator and perform an effective jarring event. To enable this, a wireline linear actuator can be used to pull and energize the accelerator and fire the jar effectively. In addition, having a jar and a linear actuator combined on the same run can allow for a more efficient fishing strategy by combining jarring and a straight pull or push. To prove the feasibility of this method, a system integration test was performed in which the linear actuator was used to fire the high-performance jar through an accelerator. In this test, the jarring force and the acceleration of the fish (the element being jarred) was measured and compared to standard jarring without the linear actuator. The measurements showed that it does not make a difference whether the jar is fired by the cable or by the linear actuator; the same force and acceleration (i.e., shock level) was imparted. This means that the linear actuator can be used to fire the jar without losing effectiveness. To achieve maximum efficiency, jarring and straight-pulling can be combined in the same run during which the two can be alternated to maximize results. This method is novel because it enables jarring in highly deviated wells and allows for jarring and straight-pulling on the same run, creating a more comprehensive fishing strategy.
