Float Collars

Non-Rotating Float Collar (Single/Double Valve)

The Non-Rotating Float Collar is designed to provide reliable back-pressure prevention during cementing operations. Attached at the end of the casing string, it prevents cement slurry from flowing back into the casing. The collar features an advanced anti-rotation mechanism, enhancing drill-out performance and ensuring a secure and efficient cementing process.

Constructed with high-quality materials, the valve is made of rubber and polymers with excellent tensile strength, ensuring durability under demanding wellbore conditions. The internal components are easily drillable, facilitating seamless operations. Available in single or double valve configurations, the float collar meets diverse application requirements.

Key Features:

  • Anti-Rotation Mechanism: Improves drill-out performance and operational efficiency.
  • Durable Construction: Made from rubber and polymer materials with high tensile strength.
  • Versatile Valve Options: Single and double valve configurations to suit various applications.
  • Wide Size Range: Available in 2 7/8″ to 30″ sizes, with custom sizes available upon request.
  • Enhanced Performance: Prevents backflow of slurry and ensures reliable cementing operations.

The Non-Rotating Float Collar is designed to meet rigorous industry standards, making it a dependable choice for challenging wellbore environments.

Conventional Float Collar (Single/Double Valve)

The EOT Conventional Float Collar is engineered to ensure reliable performance in cementing operations across vertical, horizontal, and deviated wells. Equipped with a plunger valve as standard, this float collar prevents slurry backflow and allows for maximum circulation rates.

Constructed from seamless casing-grade steel, the float collar can be manufactured in a variety of steel grades, including K-55, L-80, N-80, C-95, T-95, and P-110. Its valve system comprises high-strength polymer materials with natural rubber coating on a phenolic base, ensuring durability and resistance to harsh wellbore conditions. Encased in a high-pressure cement mixture, the valve offers dependable performance while being fully drillable.

Key Features:

  • Plunger Valve Design: Ensures maximum circulation rates and prevents slurry backflow.
  • High-Quality Materials: Manufactured using seamless casing-grade steel and durable polymer valve systems.
  • API Compliance: Designed and tested to meet API SPEC 10F standards for reliability and safety.
  • Versatile Applications: Performs effectively in vertical, horizontal, and deviated wells.
  • Customizable Options: Available in sizes ranging from 2 7/8″ to 30″, with custom sizes available upon request.
  • Drillable Components: Ensures easy removal during drilling operations.

The EOT Conventional Float Collar is the ideal solution for consistent and efficient cementing operations, offering robust performance in a wide range of well environments.

What is a Float Collar in Oil & Gas Wells?

A float collar is installed in the casing string above the float shoe during cementing operations. It serves as a one-way valve that:

  • Prevents cement slurry from flowing back into the casing
  • Maintains hydrostatic pressure control
  • Supports proper cement placement
  • Enhances zonal isolation

Float collars are critical components in ensuring long-term well integrity and cementing success.
