Course Description

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.

Course Objectives

  • 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
