MT/HT Expansion
JUMP TO

GENERAL DESCRIPTION

Riteks REX-HT – MT/HT Expansion is a high-temperature, post-set expansion additive designed to improve cement system integrity while preventing shrinkage and mitigating micro-annuli and gas channeling risks. Optimized for use in wells exceeding220°F / 104°C, Riteks REX-HT – MT/HT Expansion offers reliable performance at lower loading levels compared to traditional expansion additives. It is effective across all API cement classifications and integrates seamlessly into standard cement designs without causing execution complications. Riteks REX-HT – MT/HT Expansion enhances long-term zonal isolation and bond quality, making it ideal for demanding high-temperature environments.

APPLICATIONS & BENEFITS

APPLICATIONS

APPLICATIONS & BENEFITS
Riteks REX-HT – MT/HT Expansion is best suited for high-temperature primary cementing operations where long-term well integrity and microchannel prevention are critical. Its ability to expand post-set ensures continued performance even after initial cement hardening, making it an ideal choice in formations prone to temperature-induced stress or channeling.
