Implication

Field study demonstrates significant increase in near-wellbore permeability in carbonate reservoirs, indicating advantages of a polymer-free delayed acid system under harsh conditions.

Key Points

The polymer-free delayed acid system increased post-stimulation injectivity by 592%, enhancing near-wellbore permeability.
Innovative formulation allows deep penetration and effective acid placement in carbonate reservoirs experiencing high temperatures.
A structured production testing program achieved an average stable rate of 500 bbl/day after treatment, doubling pre-treatment outputs.
The project provides a scalable blueprint for addressing challenges in stimulating low-permeability reservoirs using advanced chemical engineering.
