FredDupriest retired last year as the Chief Drilling Engineer for ExxonMobil.    He graduated from Texas A&M with a BS in Mechanical Engineering in 1977 and spent the first 24 years in a variety of
operational assignments around the world.  For the last 12 years he was an advisor in ExxonMobil's Technical drilling organization supporting the global drill teams in well planning and trouble
response, and the development of new operational practices.  Fred has published 21 SPE papers that introduced new operational concepts.  These include the ExxonMobil’s FCS Practices for treating lost returns, and the Fast Drill ProcessTM and Limiter RedesignTM workflows. Fred is an AADE Drilling Fluids Hall of Fame inductee and was recently selected for the 2013 SPE Drilling Engineer Award.  


After retiring in May, Fred and Shirley moved to College Station where they are pursuing their lifelong dream of being young again. 

Full Description

HydrostaticPackers are not a mechanical tool, but an operational practice.  They consist of a column of light fluid, the length and density of which is engineered to allow precise control of the placement of pills, cement, and other fluids in wells that will not stand full due to low integrity.  The primary cause of failure in the treatment of lost returns is overdisplacement and the use of hydrostatic packers has resulted in a very high success rate in even the most severe lost returns events.  They have been used in operations for 17 years and have greatly affected well control practices, vugular loss practices, and cementing success in low integrity.  These practices were built on some unique insights related to pressure behaviors during loss events, and field
application requires operations training and engineering oversight.
