Training Acidizing Applications in Sandstones and Carbonates

Training Acidizing Applications in Sandstones and Carbonates

Course Description

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.

Course Objective

You will learn how to:

  • Assess a well’s need for stimulation
  • Recognize the strengths and limitations of acidizing
  • Investigate production problems from the standpoint of damage removal and improvement in well production
  • Apply acid treatments strategically to improve success
  • Approach acidizing applications from a practical viewpoint
  • Recognize opportunities for enhancement of acidizing treatments using non-acid fluids

Who Should attend?

Engineers and other personnel involved with the daily operation and management of producing oil and gas wells; production engineers and reservoir engineers involved with well stimulation applications would also benefit from attending this course.
