Proppant prevents salt precipitation, eliminates freshwater injection costs

Harts E&P, September 2018

CARBO engineered SALTGUARD technology is uniformly distributed with interconnected porosity in the proppant. The proppant is infused with a halite inhibitor and is then encapsulated to ensure a controlled release of the halite inhibitor on contact with produced water. This technology prevents salt precipitation from the fracture through the surface equipment and eliminates freshwater injection costs. SALTGUARD technology is cost-effective due to reducing the amount of chemical washout; preventing production impairment; eliminating costly remediation treatments, equipment failures and production loss from halite scaling in the fracture; and removing freshwater consumption and associated disposal cost. SALTGUARD has low minimum inhibitor concentration and is effective in brines with a presence of calcium and iron.
