Hydraulic Liner Systems
Desert Diamond International provides a range of advanced Hydraulic Liner Systems, which are critical components in well completion, particularly in challenging environments such as deepwater and high-pressure high-temperature (HPHT) wells. These systems are designed to improve well integrity, optimize cementing operations, and ensure the efficient deployment of liners in various well types.
Types of Hydraulic Liner Systems
Hydraulic Set Liner Hangers
Function: These liners are set in place using hydraulic pressure, allowing for precise control over the setting process. They are particularly effective in high-angle and horizontal wells where mechanical systems might face limitations. Materials: Typically made from high-grade steel, these hangers are designed to withstand high pressure and temperature environments. The sealing components often include elastomers resistant to chemical degradation and high temperatures. Sizes: Standard sizes range from 5 1/2 inches to 13 3/8 inches, with customization available to meet specific well requirements.
Rotating Hydraulic Liner Hangers
Function: These hangers allow for rotation during the cementing process, which helps to achieve better cement bonding and zonal isolation. This rotation is especially useful in deviated and horizontal wells where achieving uniform cement coverage is challenging. Materials: Constructed from durable steel alloys with specialized coatings to resist corrosion and wear, ensuring long-term reliability. Sizes: Available in sizes like 7 inches to 13 3/8 inches, these hangers are tailored for wells that require additional movement to ensure proper cement placement.
Expandable Hydraulic Liner Systems
Function: These systems expand once deployed, conforming to the wellbore's shape to ensure a secure and uniform seal. They are ideal for use in wells with irregular or compromised wellbores. Materials: Made from expandable steel or composite materials, these liners are designed to provide strength and flexibility, allowing them to conform to various wellbore conditions. Sizes: Common sizes include 5 1/2 inches to 9 5/8 inches, depending on the wellbore diameter and the specific application.
Material Specifications
High-Strength Steel
Used across all hydraulic liner systems, this material ensures durability and resistance to the high pressures and temperatures encountered in deep wells.
Elastomers
The sealing elements are typically made from advanced elastomers that can withstand temperatures up to 350°F and resist chemical degradation from drilling fluids.
Composite Materials
Used in expandable liners, composites provide a balance of strength and flexibility, making them ideal for wells with complex geometries.
Application in Different Types of Wells
Vertical Wells
Hydraulic liner systems in vertical wells ensure proper deployment and cementing, providing reliable zonal isolation and well integrity.
Horizontal and Deviated Wells
These wells benefit significantly from rotating hydraulic liners, which allow for movement during cementing, ensuring that the cement adheres properly to the wellbore.
High-Pressure High-Temperature (HPHT) Wells
For wells with extreme pressure and temperature conditions, hydraulic liner systems made from high-strength materials are essential to withstand the harsh environment while maintaining well integrity.
Desert Diamond International’s hydraulic liner systems are engineered to meet the rigorous demands of modern oil and gas exploration, ensuring reliable performance and enhanced well integrity across various well environments. These systems are critical in optimizing well completion operations, reducing operational risks, and extending the life of the well.
