Bridle (beam lift)

Incorrect. This is the function of the tubing and sucker rod system.

Correct! The bridle acts as the link between the beam and the polished rod, enabling the pumping action.

Incorrect. This is controlled by the downhole pump and valves.

Incorrect. The beam is supported by its own structure and the foundation.

Incorrect. Chains are not typically used in bridles.

Correct! The wire rope is the core element of the bridle, providing strength and flexibility.

Incorrect. Hydraulic cylinders are used in other pump jack components but not in the bridle.

Incorrect. Rubber hoses are not used in the bridle.

Incorrect. While some bridles are adjustable, the swivel's function is different.

Incorrect. This is the role of the clamps.

Correct! The swivel ensures smooth rotation of the wire rope, reducing wear and tear.

Incorrect. While it helps in reducing stress, the swivel's primary purpose is preventing twisting.

Incorrect. Single-rope bridles are a common type.

Incorrect. Double-rope bridles are used for increased strength.

Incorrect. Adjustable bridles are used for optimization.

Correct! Hydraulic bridles are not a recognized type. The use of hydraulics is primarily in the pump jack itself, not the bridle.

Incorrect. While important, this is unrelated to the bridle.

Correct! Regular inspection helps detect wear and tear, ensuring the bridle's safe operation.

Incorrect. The polished rod is replaced based on wear, not on a fixed schedule.

Incorrect. The stroke length is adjusted based on well conditions, not on a fixed schedule.

Potential Risks:

• **Wire rope failure:** A further break in the wire rope could lead to a complete failure of the bridle, disconnecting the polished rod from the beam. This would stop the pumping operation and potentially cause damage to the pump jack or other equipment.
• **Uncontrolled movement:** A weakened bridle could lead to uncontrolled movement of the polished rod, potentially causing damage to the wellhead or other equipment. This could also result in a safety hazard for workers in the vicinity.
• **Personnel injury:** A sudden failure of the bridle could cause the polished rod to fall, potentially injuring nearby workers.

Steps to Address the Situation:

1. **Immediately stop the pump jack operation.** This will prevent further damage to the bridle and potential accidents.
2. **Isolate the wellhead.** Close the wellhead valve to prevent oil flow.
3. **Assess the extent of damage.** Carefully inspect the wire rope for further damage. Check the swivel and clamps for any signs of wear or malfunction.
4. **Replace the bridle.** If the wire rope is significantly damaged or the bridle shows signs of wear, it should be replaced with a new one. Use a bridle of the correct size and type for the pump jack and well conditions.
5. **Ensure proper installation.** The new bridle should be installed correctly, following the manufacturer's instructions and safety guidelines. This includes ensuring the wire rope is properly secured to the swivel and clamps.
6. **Inspect and test the system.** Before restarting the pump jack, thoroughly inspect the new bridle and the entire system to ensure everything is functioning correctly and safely. This includes checking the proper alignment of the beam, polished rod, and bridle, as well as the proper operation of the swivel.
7. **Document the incident.** Record the date, time, and details of the incident, including the reason for the bridle replacement and the steps taken to address the situation. This documentation is important for future reference and maintenance records.
