Well Stimulation Fundamentals: Acidizing Risks & Failures | Module 6 Lesson 2

Acidizing does not fail randomly. It fails when the reaction is not controlled. This lesson breaks acidizing failure into four systems: • Reaction failure — acid reacts in the wrong place or at the wrong rate • Compatibility failure — new damage is created during treatment • Placement failure — acid does not reach the target zones • Execution failure — the design is not delivered You will learn how injection rate controls penetration, why incompatibility creates blockage, and how placement and execution determine real performance. Key insight: Acid does not know where to react. You must control it. Failure mapping: • No improvement → reaction or placement issue • Partial improvement → incomplete treatment • Decline → secondary damage • Irregular response → compatibility or execution problem Final principle: Do not evaluate an acid job at pump-off. Evaluate it after cleanup and sustained production. Disclaimer: The information presented in this course is provided for educational and informational purposes only.
