The patent-pending DiVert® acidizing diverter represents a novel economic approach in the acidizing industry. The DiVert additive is an engineered solution with distinct particle size distributions that effectively bridge and seal fractures and pore throats. DiVert's larger and stronger particle sizes optimize diversion when compared to conventional acidizing treatments such as rock salt and viscoelastic diverters. The DiVert technology is designed to provide maximum diversion for sandstone and carbonate acid stimulation. The DiVert additive is 100% soluble in hydrocarbons and is gradually soluble in aqueous fluids.
