Dr John Hargreaves, Managing Director

john_hargreaves_125x125John founded PEAK Global Consultancy in 2011, with the primary purpose of supplying oil and gas operators with the chance to optimise design, increase production, maximise profit and defer abandonment of their assets. His position is well founded, having honed a wealth of over 30 years experience in the oil and gas industry.

Initially, John’s PhD dissertation investigated the application of centrifugal technology to oil in water separation. He has since worked for a variety of operators, contractors and as a consultant, developing concepts and technologies to improve asset production, performance and safety. This culminated in seven years as Wood Group PSN’s Chief Process Engineer, where he managed a team of 150 engineers.
