The casing head, when installed, is typically tested to very strict pressure and leak-off parameters to ensure viability under blowout conditions before any surface equipment is installed.

2. Casing Spool: acts as a spacer between the Casing Head and the BOP or Christmas tree.

3. Casing Hanger: This is designed to support the weight of the casing strings and provide a pressure seal.

 

 

1. Slip Type:

In slip-type Casing heads, the bottom connection relies on a slip mechanism that grips and secures the casing string. This type of connection is particularly useful in situations where the casing weight needs to be supported or transferred. it offers a tight seal and can accommodate a range of casing sizes, making them versatile for different well designs.

2.Thread Type:

Thread-type Casing Head features a threaded bottom connection that allows for secure attachment to the casing string. This type of connection provides a reliable and robust seal, making it suitable for high-pressure applications. it is generally easier to install and remove compared to other types, facilitating maintenance and repair operations.

 

3. Welded Type:

Welded-type features a bottom connection that is welded directly to the casing string. This type of connection provides an exceptionally strong and leak-proof seal, making it suitable for high-pressure and high-temperature applications. it is often preferred in harsh downhole environments where maximum integrity is required. However, they may be more challenging to install and remove compared to thread or slip-type connections.

 

Each type of Casing Head Assembly has its advantages and is selected based on factors such as well design, pressure requirements, casing weight, and operational conditions. Vigor offers multiple options to cater to diverse customer needs and ensure compatibility with existing well infrastructure.

 

 

1. Robust Construction: Casing Head Assemblies are engineered to withstand extreme downhole conditions, including high pressures, temperatures, and corrosive environments. They are typically manufactured from high-strength alloy steels and can be coated with corrosion-resistant materials for enhanced durability.

 

2. Pressure Integrity: The assembly incorporates advanced sealing mechanisms, such as metal-to-metal seals, elastomeric seals, or a combination of both, ensuring a reliable pressure seal between the casing strings and the wellhead.

 

3. Customizable Design: they are available in various sizes, pressure ratings, and configurations to accommodate different well designs and operational requirements. Common sizes range from 11 inches to 21 1/4 inches, with working pressure ratings from 2,000 psi to 5,000 psi.

 

4. Multiple Outlet Options: The Casing Head features side outlets, which can be used for various purposes, such as pressure monitoring, well intervention, or cementing operations. These outlets can be configured with line pipe connections, flanged connections, or studded connections.

 

5. Easy Installation and Maintenance: The assembly is designed for efficient installation and retrieval, with features like lockdown screws or rings to secure the Casing Hanger and facilitate maintenance or replacement when necessary.
