Sand Pump Bailer- Stroke Bailer
To remove unwanted debris from wellbore.
Assemble the Sand pump with the desired shoe (ball / flapper) and hoist into lubricator. Lower into wellbore to top of debris. Gently set down on top of debris until the stroke section of the bailer is closed, attempt to retrieve debrisby opening and closing the stroke bailer, thus creating a vacuum and filling the load barrel with debris. Once the load barrel has been filled, remove equipment from wellbore and empty any debris from the load barrel.
The sand pump should be periodically pulled from debris so as not to get stuck or trapped in material that is being bailed. Always ensure that when emptying the sand pump that all threads are clean and free from debris as to prevent damage to the threads when assembling.
