Microfume 102 DM is an extender for lightweight cements and a compressive-strength enhancer for low-temperature, lightweight cements.

REX-HT – Post Set Expansion Cement Additive

REX-HT is a post set expansion additive developed for use at temperatures above 170°F (76.7°C). REX-HT additive helps control microchannels, which provide a pathway for interzonal communication. The expansion provided by REX-HT additive develops as a function of temperature, which accelerates expansion. Features and Benefits

• Performs well in areas with suspected micro channeling problems with minimal design and job execution problems
• Non-hazardous in normal working conditions

REX-LT – In-Situ & Post Set Expansion Cement Additive

REX-LT Cement Additive is a chemical expansive additive developed for use at temperatures from 100° to 210°F (37°C to 99°C). REX-LT offers both In-Situ Expansion as well as Post Set Expansion with lower loading levels than traditional alternatives, and provides early strength development and shortens Static Gel Strength Time. Its expansion properties help to provide a better bond and shrinkage control prevents the possibility of channeling. REX-LT also has some very desirable secondary effects, including improvements in Fluid Loss and Free Fluid properties. Features and Benefits

• Improved bonding and zonal isolation possible
• Helps prevent shrinkage and channeling
• Non-hazardous in normal working conditions
• Improved fluid loss numbers
• Slight gains in viscosity
• Shortening of total thickening time
• Lower free fluid

RadiLock 1.8mm & 3mm Acrylic Fibers – Mechanical Improvement Fiber

Next generation fiber technology proven to significantly increase the mechanical properties providing more durable, longer lasting cement for the life of the well.  The fiber count, specific gravity, strength, and bonding with cement enhances and improves mechanical properties including tensile strengths, flexural modulus, & stress/strain on the cement. Features and Benefits

• Lost circulation properties
• Field tested to be effective for returning circulation in porous formation
• Effectively bridges gaps and aids in support & suspension of the slurry design
• Demonstrated good improvements to bond logs- aids in preventing shrinkage of the cement.
• Material is easily dry-blended or hand dosed
• Has little effect on the rheology & viscosity of the cement slurry
• Becomes part of cement matrix by interacting with bot water and cement phases due to carboxyl groups in the acrylic fibers
• Significantly outperforming nylon and polypropylene based LCM fibers

Riteks RCD-4 – Polymer Based Dispersant

Riteks RCD-4 provides superior dispersing power compared to conventional dispersants up to minimum 250°F (120°C). RCD-4 is a high-range water-reducing admixture powder utilizing superior polycarboxylate chemistry to achieve low and stable rheology at significantly lower dosage rates than with standard dispersants. This chemistry also offer a very high salt tolerance up to 18% NaCl & widens the field of potential applications significantly. RCD-4 can show retarding properties, although is often used in CaCl2 accelerated cement slurries and aids in reducing shrinkage during accelerated cement set. Features and Benefits
