Kickover Tool

Kickover Tool: A Vital Component in Gas Lift Operations

In the oil and gas industry, retrieving stuck tools or equipment from wells is a common challenge. The "Kickover Tool" plays a critical role in overcoming this hurdle, specifically in gas lift operations. This specialized tool serves as a crucial link between the wellhead and the stuck equipment, allowing for its safe and efficient removal.

What is a Kickover Tool?

Essentially, a Kickover Tool is a fishing tool designed to "kickover" or decentralize the retrieving tool. It functions by creating a lateral force that shifts the retrieving tool away from its stuck position. This lateral force allows the retrieving tool to gain leverage and overcome the resistance encountered in the wellbore.

How does it work?

The Kickover Tool is typically attached to the end of the retrieving tool, with a specialized mechanism designed to create the lateral force. This mechanism can vary depending on the specific design of the tool, but generally involves a cam, a wedge, or a rotating element.

As the retrieving tool is lowered into the wellbore, the Kickover Tool engages with the stuck equipment. The mechanism then applies a force that shifts the retrieving tool, allowing it to move past the obstruction.

Key Applications in Gas Lift:

The Kickover Tool finds extensive application in gas lift operations. This method of oil production utilizes injected gas to push oil to the surface. Stuck equipment in gas lift systems can significantly hinder production, and the Kickover Tool provides a reliable solution for their removal.

  • Stuck tubing: The Kickover Tool can be employed to retrieve stuck tubing that has become lodged in the wellbore due to wear, corrosion, or other factors.
  • Stuck packers: Packers are essential components in gas lift systems, sealing off different sections of the well. If a packer becomes stuck, the Kickover Tool can help in its retrieval.
  • Other stuck equipment: The tool can also be used to retrieve various other equipment that may become stuck in the wellbore, including valves, tools, and even parts of the gas lift system itself.

Benefits of using a Kickover Tool:

  • Increased Retrieval Success: The lateral force created by the Kickover Tool significantly improves the chances of retrieving stuck equipment.
  • Reduced Risk of Well Damage: By decentralizing the retrieving tool, the Kickover Tool minimizes the risk of damaging the wellbore during the retrieval process.
  • Cost-Effectiveness: The tool's effectiveness in retrieving equipment quickly can lead to reduced downtime and production losses, ultimately resulting in cost savings.

Conclusion:

The Kickover Tool is a valuable asset in the oil and gas industry, particularly in gas lift operations. Its ability to safely and efficiently retrieve stuck equipment minimizes downtime, reduces wellbore damage, and ultimately contributes to smoother and more cost-effective oil production.

Exercise: Solving a Gas Lift Problem

Scenario: A gas lift well experiences a sudden drop in production. Upon investigation, it is found that a packer has become stuck in the wellbore, preventing the injected gas from reaching the desired production zone.

Task:

  1. Identify the problem: What specific issue is hindering production?
  2. Propose a solution: How can a Kickover Tool be used to address the problem?
  3. Explain the benefits: What advantages does using a Kickover Tool offer in this situation?

Exercice Correction

**1. Identify the problem:** The stuck packer is preventing gas from reaching the production zone, leading to a drop in oil production.

**2. Propose a solution:** Use a Kickover Tool attached to a retrieving tool to dislodge the stuck packer from the wellbore. The tool's lateral force will help shift the packer, allowing it to be retrieved.

**3. Explain the benefits:** - **Increased Retrieval Success:** The Kickover Tool increases the chance of successfully retrieving the stuck packer. - **Reduced Risk of Well Damage:** The tool helps minimize the risk of damaging the wellbore during the retrieval process. - **Cost-Effectiveness:** By quickly retrieving the packer, the tool helps minimize downtime and production losses, resulting in cost savings. - **Production Restoration:** Releasing the stuck packer will restore gas flow to the production zone, increasing oil production.
