Course description

Acidizing Applications in Sandstones and Carbonates - ASC

Although acidizing is the oldest method of well stimulation, it is often applied with mixed results. It remains, however, a valuable tool for improving well productivity. The key to acidizing success is in the understanding of how it works, the optimum conditions for its application, and proper evaluation of well response after the acidizing treatment. The instructor will present many of the practical aspects of acidizing applications and help provide a better understanding of acidizing as a tool for enhancing well performance.

For the virtual session, class hours will be 0800-1200 CDT (GMT - 5:00) on Monday, Wednesday, and Friday of each week.

"The materials in the book are well written, and the slides provide excellent guidelines and rules of thumb that a young engineer can take and apply." - Production Engineer, United States

"Most topics are informative and useful, including sandstone acidizing, acid fracturing, additives, etc. I appreciated Alfred's clarification of [participants'] questions from previous day." - Senior Research Engineer, United States
