Characterize scaling damage from pressure measurements

Abstract

Productivity-decline prediction is based on mathematical modeling with wellknown model coefficients. The sulphate-scaling system contains two governing parameters: the kinetics coefficient, λ, characterizing the velocity of chemical reaction, and the formation damage coefficient, β, showing how the permeability decreases because of salt precipitation. This paper extends previous works with commingled injection of two incompatible waters into the same core with two different ratios of formation water (FW) to seawater (SW).
