PSE Oil & Gas key technical personnel

James Marriott PhD CEng MIChemE, VP PSE Oil & Gas

James MarriottJames Marriott is Head of PSE's Oil & Gas business unit. He is a Chartered Engineer with a PhD in advanced mathematical modelling and optimisation from University College London.

James has over 15 years' experience in developing mathematical modelling solutions for a wide range of industries, and has managed projects and initiatives from delivering solutions that improve the efficiency of a company's processes and the quality of its products to supporting critical decisions on the safe design and operation of processing plants.

James also advises companies on the best strategies to create world-class modelling infrastructures required to meet their innovation, development and, ultimately, business targets. He led the development of PSE's next generation approaches for the safe design and operation of pressure relief and blowdown systems.

Relevant publications include several on the optimal design and operation of separation processes and a number of recent articles on high-fidelity dynamic modelling techniques for process depressurisation, plant blowdown and flare system analysis.

Apostolos Giovanoglou PhD, Technical Director

Apostolos GiovanoglouApostolos is responsible for the development of PSE's gFLARE advanced depressurisation technology and for the delivery of related services. He is a Chemical Engineer with a PhD in thermodynamics and phase equilibrium from Imperial College London.

Apostolos has 14 years of experience in advanced process modelling projects including dynamic modelling of relief and blowdown systems; well start-up with a gas cap; KO drum low temperature analysis; simulation of HIPPS systems, and whole-plant simulation and optimisation studies.

Publications, among many others, include several on fluid phase stability and equilibrium calculations published in Fluid Phase Equilibria, and related presentations at the PPEPPD 2004 and Thermodynamics 2005 conferences.

Malcolm Woodman, Senior Advisor, Production Optimisation

Malcolm WoodmanDr Malcolm Woodman started consulting for PSE in 2016, after more than 25 years with BP. For the last 10 years at BP, Malcolm was Project Manager, Programme Manager and Technical Lead for the use of model-based optimisation in BP Upstream. His key responsibility was the development of systems to allow the use of commercial production modelling packages for production optimisation on the operating assets, not just by central modelling specialists. Malcolm is the author / co-author of many peer-reviewed journal papers and conference presentations, covering topics ranging from three phase distillation, use of thermodynamics packages in industry, use of the CAPE-OPEN interfaces and production optimisation.

Costas Pantelides, Strategic Advisor

Costas Pantelides Professor Costas Pantelides FIChemE FREng is the Managing Director of PSE and also a part-time professor of chemical engineering at Imperial College London. He holds BSc (Eng) and PhD degrees from Imperial College and a Masters degree from MIT.

With 30 years' experience in process modelling technology, he is one of the world's foremost authorities in this area, having played a leading role in the design and development of the gPROMS® and SPEEDUP® software. He has been the winner of the 1998 Beilby Medal and Prize, awarded jointly by the UK Society of Chemical Industry, the Royal Society of Chemistry and the Institute of Materials for his contributions to process systems engineering, and of the 2007 Royal Academy of Engineering MacRobert Award, the UK's most prestigious prize for engineering innovation.

Costas plays an active role in formulating PSE's strategy for Oil & Gas. On the technical side, his main involvement is in the design of novel tools that integrate mathematical models, advanced computational techniques and sophisticated software architectures to address problems of relevance to this sector.
