An exothermic chemical reaction between the fluids increases the oil temperature and decreases the viscosity. As a result, the displacement is accelerated. Acidizing involves injecting an acid solution into a porous formation at a pressure below the fracture pressure. The acid dissolves part of the rock and contaminants, forming a network of channels diverging from the wellbore. It increases the permeability of the porous medium. The reaction products are highly soluble and do not precipitate. After acid injection and well startup, they are removed with the product. ER -
