Granular polymer that expands in water to help restrict fluid loss through coarse pores and voids.
Swellable Polymer Lost-Circulation Material is used to seal large flow paths in gravel, fractured and unconsolidated formations. The granules take up water and expand into a flexible plug within the void.
Expansion time and final particle size must be considered against downhole equipment clearances. Avoid holding the product in surface lines before it reaches the target and run a small compatibility test.
