REX-LT is a next-generation in-situ expansion additive designed to enhance zonal isolation and cement integrity at significantly lower loading levels than traditional expansion materials. Engineered to activate during the cement
setting process, REX-LT supports early strength development and shortens Static Gel Strength (SGS) transition time. Its expansion behavior prevents shrinkage, minimizes the risk of channeling, and improves the overall bond
between the cement sheath and casing or formation. In addition to its primary expansive functionality, REX-LT also contributes secondary performance benefits such as enhanced fluid loss control and improved free fluid properties in certain formulations—offering both performance and cost efficiencies in a single solution.
