Differences in reservoir permeability can lead to poor acidizing results. The use of viscoelastic diverting acid during acidizing can help increase production.

At the initial stage of treatment, acid preferentially enters high-permeability zones or natural fractures. As the viscosity of the acid fluid increases, these zones effectively become “low-permeability formations.” Acid then begins to enter the previously low-permeability zones, which in turn become relatively higher-permeability formations.

This intelligent viscosity-switching effect enables more uniform acidizing across the entire reservoir interval, unlocking the production potential of low-permeability formations.
