Hydrofracking of Shales and Associated Internal Corrosion Problems Course

Pat Teevens

This professional training course focuses on the critical but often overlooked issue of internal corrosion in hydrofracked shale wells. Participants will explore the mechanisms behind corrosion problems related to hydrofracking operations, including the impacts of oxygenated frac water and flowback water on downhole tubulars and pipelines. The course covers detection methods, mitigative strategies, and regulatory requirements to help manage corrosion risks effectively. It emphasizes practical on-site testing procedures and provides insights into corrosion management systems necessary to maintain pipeline and wellbore integrity. The content is suitable for various levels from fundamental to advanced and spans disciplines such as production, development, and facilities engineering.Read more...
