Mechanical Liner Systems
Desert Diamond International provides advanced Mechanical Liner Systems, which are integral to well completion operations, particularly in environments where hydraulic systems might be less practical or where mechanical reliability is paramount. These systems are designed to anchor liners securely within the wellbore, ensuring effective isolation of zones andproviding structural support for the well.
Types of Mechanical Liner Systems
Mechanical Set-Flex Liner Hanger
Function: This tool is used to suspend a liner within the wellbore using mechanical force. It is set by rotating the running string, which engages the slips and anchors the liner in place. This type of hanger is especially useful in wells where control over the liner setting process is critical. Materials: Made from high-quality API 5CT standard materials, often featuring components resistant to H2S or CO2 environments, ensuring durability in corrosive conditions. Sizes: Available in sizes ranging from 4 1/2 inches to 13 3/8 inches, these hangers can be customized to fit specific well requirements.
Rotating Mechanical Liner Hanger
Function: Designed for wells that require rotation during cementing, this hanger allows for the liner to be rotated once it is set in place. This rotation improves cement bonding and ensures better zonal isolation. Materials: Constructed from durable steel alloys with protective coatings to resist wear and corrosion, making them ideal for use in harsh downhole environments. Sizes: Typically available in sizes from 7 inches to 13 3/8 inches, suitable for various wellbore diameters.
Mechanical Liner Hanger with Integrated Packer
Function: This system integrates a liner hanger with a packer, providing a dual function of securing the liner and isolating the annulus. It is set by mechanically engaging the packer elements, which expand to seal the annular space. Materials: Uses high-strength steel for the hanger body and advanced elastomers for the packer elements, ensuring both durability and effective sealing. Sizes: Available in multiple sizes, typically from 5 1/2 inches to 13 3/8 inches, with customization options depending on the specific needs of the well.
Material Specifications
High-Strength Steel
Ensures the durability and structural integrity of the liner systems, even under high-pressure conditions.
Elastomers
Used in the packer elements and seals, these materials are selected for their resistance to high temperatures and corrosive substances, ensuring long-term reliability.
API 5CT Standard Materials
Commonly used for the main components, ensuring compliance with industry standards and compatibility with other well components.
Application in Different Types of Wells
Vertical Wells
Mechanical liner systems are commonly used in vertical wells to provide effective zonal isolation and to support the liner during cementing operations.
Horizontal and Deviated Wells
In these challenging environments, rotating mechanical liners are particularly beneficial as they allow for better cement placement and zonal isolation.
High-Pressure High-Temperature (HPHT) Wells
In high-pressure, high-temperature environments, mechanical liner systems made from high-strength materials are essential to maintain well integrity and prevent failures.
Desert Diamond International’s mechanical liner systems are engineered to meet the demanding requirements of modern oil and gas exploration, ensuring reliable performance and enhanced well integrity across a wide range of drilling environments. These systems are critical in optimizing well completion operations, reducing operational risks, and extending the life of the well.
