After graduation (BSc in Chemical Engineering from Abadan Institute of Technology, Iran), he joined National Iranian Oil Company (NIOC) in 1984 where he worked as Production Engineer as well as University Lecturer for seven years.  Bahman Tohidi joined Heriot-Watt University in 1991 and graduated with a PhD in Petroleum Engineering in 1995 with his doctoral work on the phase behaviour of water-hydrocarbon systems and gas hydrates. He started his employment at Heriot-Watt University in January 1994 working in both Hydrate and Reservoir Fluids research projects.


His research interests include gas hydrates, flow assurance (e.g., wax, asphaltene, salt, emulsion, foam, etc), PVT, phase behaviour and properties of reservoir fluids and H2S/CO2-rich systems, production technology and EOR. Currently, he leads Hydrate, Flow Assurance and Phase Equilibria Research Group at Institute of Petroleum Engineering, Heriot-Watt University. He is the Director of International Centre for Gas Hydrate Research and the Centre for Flow Assurance Research (C-FAR) at Institute of Petroleum Engineering, Heriot-Watt University with several projects on various aspects of gas hydrates and flow assurance, and phase behaviour and properties of reservoir fluids and H2S/CO2-rich systems. His is a consultant to major oil and service companies. Bahman is Managing Director of “HYDRAFACT LIMITED” a Heriot-Watt spin-out Company formed in 2006 with Flow Assurance and PVT as its main area of activity.  Hydrafact played a major role in Heriot-Watt University winning the Queen’s Anniversary Awards in 2016.


His teaching activities included Petroleum Engineering and Production Technology, as well as offering several short courses to the industry (including; Flow Assurance and Gas Hydrates, PVT and Phase Behaviour of Reservoir Fluids, and Petroleum Engineering for other Disciplines). He taught Production Technology for 10 years to Heriot-Watt MSc students in Edinburgh and various Approved Learning Partners in Russia, China, Azerbaijan, Kazakhstan, Malaysia, and Angola.  He has published more than 400 papers and holds 10 patents mainly in gas hydrates and PVT. He was SPE Distinguished Lecturer in 2004-2005 with his talk entitled, “Gas Hydrates: Friend or Foes?”. Bahman is a Professor at the Institute of Petroleum Engineering, Heriot-Watt University. Bahman is a member of the Society of Petroleum Engineers. He was member of the EPSRC (the UK Engineering and Physical Science Research Council) Peer Review College for 2006-2009 and 2010-2013 and former member of editorial board of Journal of Chemical Engineering Research and Design (2009-12), and former-Deputy Head of Institute of Petroleum Engineering, Heriot-Watt University (Oct 2012-May 2014).
