As the acid is progressively spent to near completion, calcium sulfate can precipitate out as needle-like crystals. If this occurs in the formation or during flowback, the newly-etched channels created by the stimulation treatment can become blocked, decreasing permeability. Traditionally, addressing the issues associated with anhydrite inhibition has involved a two-step process using HCl blends with calcium chloride salt and a scale inhibitor. Trican’s SI-10 is an efficient and effective one-step scale inhibitor that works in a variety of well types. SI-10 is designed to reduce the dissolution of the anhydrite and prevent precipitation that may occur after the acid has spent without the use of calcium chloride, saving both time and money. Advantages Reduces dissolution and prevents precipitation of anhydrite in one step, without calcium chloride Added at 1 to 2 L/m 3 , reducing the amount of calcium sulfate dissolved by approximately 50% Specially formulated for high salinity brines and acid solutions Cost savings from 8 – 24% For more information, please contact Trican Well Service. 1315/031715 Scale Inhibitor CaSO 4 Dissolved SI-10 Concentration Precipitation of CaSO 4 * Blank 1.50 0 Present Blank with CaCl 2 0.17 0 Present Blank with CaCl 2 and SI-10 0.00 1 L/m 3 Not Present Blank with SI-10 0.71 1 L/m 3 Not Present
