Acid treatment design has moved well beyond rules of thumb. Core flood testing gives pore volume to breakthrough curves that define optimum injection rate for a specific rock. Conductivity testing under closure stress shows whether an acid-etched fracture will stay open in a soft carbonate. Inhibitor qualification at bottomhole temperature shows whether tubing will survive the job. Where these tests are done, treatment results are predictable; where they are skipped, results vary from well to well without explanation.

Simulation adds the ability to test design choices before pumping. Matrix acid models predict wormhole penetration and skin evolution along an interval. Acid fracture models predict fracture geometry, acid penetration distance, etching and resulting conductivity. Both depend on the laboratory data that feeds them, which is why testing and simulation belong together.

The final step is field execution. A design is only as good as the fluids mixed at the wellsite, the rates achieved, the diversion that works and the flowback that recovers spent acid before it precipitates. This course connects all three stages, from laboratory bench to field result, and covers how to evaluate whether the design assumptions held.

By the end of this training, participants will be able to:

• Plan a laboratory testing programme to support acid treatment design.
• Interpret core flood and wormhole efficiency data for treatment design.
• Qualify corrosion inhibitors and screen additive compatibility for well conditions.
• Select acid systems for high temperature, tight, and acid-sensitive formations.
• Design acid fracturing treatments, including fluid loss control and etching.
• Predict acid fracture conductivity and its retention under closure stress.
• Apply matrix and fracture acidising simulation and understand its input requirements.
• Design placement and diversion strategies for long and horizontal intervals.
• Translate laboratory and simulation results into field procedures and control limits.
• Evaluate treatment results against design predictions.
