Composition and Properties of Drilling and Completion Fluids

Nicknamed "Slim Darley", the late H.C.H. Darley was formerly a member of the Institute of Petroleum in London, an active member within SPE, and a Researcher for Shell for almost 25 years as well as a Consultant. Darley earned a BS degree in Petroleum Engineering from Birmingham University in the UK, and Mr. Darley passed away in 1996. The late George Gray, or "Doc Gray", as he was known in the industry, was a drilling fluids technologist for NL Baroid for over 30 years and a pioneer in the development of drilling fluids technology. He willingly served on innumerable committees and held various offices in technical societies, including Director and Vice President of SPE and various poistions within the American Chemical Society and American Petroleum Institute. George earned a BS degree from Texas Christian University and a MS and PHD degree from Rice University and was a registered professional engineer in the state of Texas. George passed away in 1983.
