Scenario:
A packer has become stuck in a wellbore due to cement bridging. The operator decides to use a Cherry Picker to retrieve the packer.
Task:
**1. Steps involved in using a Cherry Picker:** * **Lowering the Cherry Picker:** The Cherry Picker is lowered into the wellbore, using a wireline or tubing string. * **Overshot Engagement:** The overshot jaws are designed to securely grasp the packer's upper slips. * **Milling Action:** The bottom cutter surface of the tool begins milling away the top slips or even all of the slips. This action creates a clear path for the packer retrieval. * **Extraction:** Once the slips are removed, the Cherry Picker allows the packer to be lifted out of the wellbore, freeing the well. **2. Preventing Damage to the Wellbore:** The milling action of the Cherry Picker is carefully controlled to remove only the necessary amount of material. This precision minimizes the risk of damaging the wellbore, unlike other fishing techniques that can cause significant damage. **3. Factors to Consider:** * **Nature of the Stuck Packer:** If the packer is heavily cemented in or there is a severe risk of wellbore damage, other fishing techniques might be more appropriate. * **Wellbore Conditions:** The wellbore's size and condition should be considered to ensure the Cherry Picker can operate safely and effectively. * **Cost and Time:** The cost and time required to use a Cherry Picker should be weighed against alternative solutions. * **Availability of Equipment and Skilled Operators:** Access to a suitable Cherry Picker and skilled operators is crucial for successful retrieval.
