Current Position: NALCO – Industry Development Manager

SUMMARY

An Industry Development Manager on Global Water Management for Nalco Energy Services and the Scientific Development Advisor to the Board of the Middle East-Africa-Asia Produced Water Community. Until November 2009, he served as a Scientific Advisor with Halliburton’s Conformance Technology/Production Enhancement Group in Duncan, OK. He has over 30 years experience with in depth expertise in all phases of water control and well preparation including conformance technology, clay control, and improved oil recovery methods as well as the development and implementation of those technologies. He has successfully consulted on procedures and job recommendations around the world. His most recent work led to development and application of several novel chemical systems for water shut-off, gas shutoff, and improved wellbore integrity. He has authored hundreds of publications on these topics and holds over 30 patents related to Conformance technology, acidizing, sand control, fracturing and cementing.
