This course provides a broad overview of the nature of formation damage problems, how they occur during various oilfield operations, and their effects on well productivity. It reviews basic rock properties affected by formation damage, discusses the types and mechanisms of formation damage, evaluates economic implications, and integrates field and laboratory methods for recognition of the damage. Also, it Provides geological and engineering techniques for proper evaluation of the problem and procedures to minimize / alleviate it.

• Recognizing formation damage problem during any stage of well development and reservoir exploitation.
• Evaluating drilling and completion practices to establish procedures for selection of non-damaging systems.
• Developing procedures to assess and integrate laboratory and field techniques to recognize and treat formation damage.
• Quantify the annual revenue loss associated with formation damage.

• Petroleum Engineers,
• Reservoir Engineers,
• Production Engineers,
• Drilling Engineers,
• Reservoir Geologists, and
• Petrophysists.
