Water Flooding Management

Magdi El Naggar

This course is designed to ensure an effective understanding of the water flooding (injection) system as one of the reservoir secondary methods of oil recovery and maintain the reservoir pressure with special attention to the system components from the supply source to the injection point in the reservoir. It involves injecting clean, non-corrosive water into the reservoir to displace the remaining oil. This training course is primarily on the mechanics of oil recovery by water flooding. The aim of this course is to provide the participants with a complete and up-to-date overview of water flooding. Upon successful completion of this training course, participants should have a solid grounding in understanding the purpose, operation, and inspection of water injection systems for enhanced oil recovery. The training course will also illustrate potential problems and solutions.

The course is composed of modules, which include exercises, group discussions, and quizzes for full comprehension of the course topics relevant to all functions of the water injection system and its operations.
