CONGO for Lost Circulation
CONGO is a swelling copolymer for lost circulation that expands over 200 times its volume in freshwater. This lost circulation additive can be added to seal fractures or spotted in caving zones to consolidate loose formations. Proven to help mitigate lost circulation issues in caisson drilling, horizontal and vertical directional drilling, tunneling, and other subsurface construction.
Can be hydrated prior to spotting and accumulates in a variety of fracture sizes due to its swelling capacity and particle size distribution.
