ISO/TS 12835:2022

What is ISO/TS 12835:2022-casing connections for thermal wells?

ISO/TS 12835:2022 is a technical specification that outlines the requirements for casing connections used in thermal wells. These wells are utilized in the petroleum and natural gas industries. That are particularly in thermal recovery operations where high temperatures are involved. The standard ensures that the connections are capable of withstanding. The challenging conditions of thermal wells, thus guaranteeing operational safety and efficiency

Key Features of ISO/TS 12835:

Material Specifications: The standard defines the materials suitable for casing connections, ensuring they can endure high temperatures and thermal cycling

Design Requirements: It provides detailed design criteria to ensure the structural integrity of the connections under thermal stress

Testing and Validation: ISO/TS 12835 includes rigorous testing procedures to validate the performance of casing connections in thermal environments

Quality Control: The specification mandates strict quality control measures during the manufacturing process to maintain consistency and reliability

Thermal wells are critical in enhanced oil recovery (EOR) processes, such as steam injection, which involve injecting steam into the reservoir to reduce the viscosity of heavy crude oil. The casing connections in these wells must withstand high temperatures and thermal stresses without failure. ISO/TS 12835 ensures that the connections meet these demands, contributing to the safe and efficient extraction of resources
