Modeling pressure response of in-situ diverting acid flow

Abstract

Examples described herein provide for modeling pressure response of acid flow of an acid in a formation. An example method includes receiving data associated with acid stimulation of a formation and modeling the pressure response of the acid flow in the formation. Modeling the pressure response is based on a model which divides a domain into multiple zones, and modeling the pressure response includes modeling a length of a disturbance zone included in the multiple zones based on a function of: reaction kinetics associated with the acid and rock included in the formation; and an injection rate of the acid, a velocity of the acid, or both. The method includes performing the acid stimulation based on a stimulation parameter associated with the data and the acid stimulation or a modified stimulation parameter, responsive to determining whether the pressure response satisfies the pressure response threshold.
