Experimental study of reaction rate constants of carbonate rocks in acid fracturing fluids

Authors: R.R. Ibatullin, V.G. Salimov, A.V. Nasybullin, O.V. Salimov (TatNIPIneft)

Key words: hydrofracturing, carbonate rocks, acid fluid, rotating disk, reaction kinetics.

Methods of kinetic parameters calculation using data from rotating disc have been analyzed. It has been shown that to calculate a rate constant and an order of reaction in surface kinetics region, optimization methods shall be used. Rate coefficients and orders of reaction of Tatarstan carbonate rocks dissolution in acid fracturing fluids under high frac pressure have been determined.
