Objectives

To provide reasonable procedures and guidelines and to offer cautions suggested by particular formation compositions and reservoir conditions. At the end of the course delegates will learn about the many processes involved in acid stimulation operations, about acidizing equipment and how to plan and execute an acid job.

The Delegates

• Drilling, completion, workover and production engineers and managers.
• Reservoir and geologyengineers, field maintenance supervisors and operators.
• Service companies and equipment manufacturing engineers.
• Safety engineers and personnel selected by their companies for attending special training courses.
