Louisiana Patent of the Month – July 2023

In the ever-evolving world of oil and gas exploration, technological advancements continue to push the boundaries of efficiency and effectiveness. One such groundbreaking innovation comes from Fortress Downhole Tools, LLC, a leading pioneer in downhole equipment. Their latest invention, a gas-operated setting tool, promises to streamline the way plugs and other downhole equipment are set within wellbores.

Traditional wireline setting tools have long been plagued by complexity and cumbersome designs. They require multiple personnel to handle, making operations time-consuming and labor-intensive. Fortress recognized the need for a compact and cost-efficient alternative, leading to the development of their cutting-edge gas-operated setting tool.

At the heart of this innovation is a pressure sub that houses an inner chamber and a mandrel operationally attached to it. An outer cylinder assembly, in fluid communication with the inner chamber, can alternate between a running position and a setting position when axial force is applied. What sets this tool apart is the inclusion of a dampening assembly, consisting of a plug housing, a moveable ball, and a dampening media. This assembly regulates the axial force applied to the outer cylinder assembly, ensuring precise and controlled operations.

The gas-operated setting tool operates by igniting a power charge within the pressure sub. As the power charge burns, it generates gas pressure that acts upon a piston surface of the outer cylinder assembly. This force causes the outer cylinder assembly to stroke from the running position to the setting position, securely setting downhole plugs and other equipment.

Fortress’ setting tool offers a compact design which make it lighter and easier to handle, eliminating the need for extensive manpower. Additionally, the absence of oil for dampening means fewer parts and seal areas, minimizing the risk of leakage and human error. This innovative setting tool is a game-changer for the oil and gas industry. Its efficiency and effectiveness will streamline operations, allowing for quicker redressing and reuse.
