Introduction:

Sand production in oil and gas wells can lead to operational challenges such as equipment damage, production loss, and wellbore instability. Sand control is essential in preventing the migration of sand from the reservoir into the wellbore, where it can cause erosion, plugging, and other production issues. This course provides a comprehensive understanding of sand control techniques, including mechanical, chemical, and reservoir management approaches to minimize sand production. Participants will learn the principles, design considerations, and applications of various sand control methods and how to select and implement the most appropriate solution based on reservoir characteristics and operational needs.
