Our Team

Managing Director

Following graduation in 1984 (BSc in Chemical Engineering, Abadan Institute of Technology, Iran), Bahman Tohidi joined the National Iranian Oil Company (NIOC), where he worked as a production engineer and university lecturer for seven years. In 1991 he joined Heriot-Watt University, graduating 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 in January 1994, working on both Hydrate and Reservoir Fluids research projects.

Prof Tohidi’s research interests include gas hydrates, flow assurance, phase behaviour and properties of reservoir fluids, and the development of low carbon energy technologies. Currently, he leads the Reservoir Fluids Research Group and is Director of the Centre for Gas Hydrate Research and the newly formed Centre for Flow Assurance Research (C-FAR) at the Institute of Petroleum Engineering, Heriot-Watt University, where he manages a wide variety of research projects on gas hydrates, flow assurance, phase behaviour and properties of reservoir fluids.

Prof Tohidi teaches Petroleum Engineering and Production Technology at postgraduate level, as well as offering several short courses to the industry. He has published more than 150 papers and currently holds 8 patents primarily concerning gas hydrate and PVT technologies. He is a Professor at the Institute of Petroleum Engineering, Heriot-Watt University, an Adjunct Professor at the University of Tehran, and an Honorary Professor at the School of Engineering and Electronics, University of Edinburgh, UK.

Prof Tohidi is a member of the Society of Petroleum Engineers, and a member of EPSRC (the UK Engineering and Physical Science Research Council) Peer Review College for 2006-2009. He was SPE Distinguished Lecturer for 2004-2005, giving high-profile presentations on gas hydrates worldwide over the course of the year.

Our History

From initial research all the way through to a private laboratory within the Heriot-Watt University Research Park

1986
Research begins

The history of Hydrafact dates back to 1986 when research into gas hydrates first began at the Institute of Petroleum Engineering, Heriot-Watt University.

Initially, hydrate studies were undertaken by the well-known Reservoir Fluids Group. However, as hydrate research grew steadily, the Hydrate Group soon emerged as a recognised research group.

1990's
HydraFLASH developed

During the 1990s, the Hydrate Group successfully undertook a variety of Joint Industry (JIP) and Government sponsored research projects related to hydrate problems in offshore oil and gas operations. Over the course of this period, the team firmly established itself within the industry and academic community as a leader in flow assurance research, with a reputation for quality experimental work and advanced theoretical studies.

Sequential JIPs supported the generation of a vast in-house library of hydrate equilibrium data, and development of the commercial hydrate predictive software, HydraFLASH which is currently used by a number of major hydrocarbon production and service companies in planning their flow assurance strategies.

Early 2000's
RDG Grant awarded

In June 2000, the Hydrate Group was awarded a prestigious Scottish Funding Council Research Development Grant (RDG) with the aim of creating a 'Centre of Excellence' in gas hydrate research and training. This led to the formation of the Centre for Gas Hydrate Research, which was formally established in February 2001.

Funding allowed the employment of new staff, expansion of laboratories and construction of new equipment, greatly increasing the breadth and scope of gas hydrate and flow assurance research at Heriot-Watt.

New laboratory constructed

In 2006, the Hydrate Group secured a major SRIF (Science Research Investment Fund) award to establish the Centre for Flow Assurance Research (C-FAR) at Heriot-Watt. This grant funded the construction of a new laboratory with a 1" diameter, (2.5 cm) 40 m length, 200 bar flow loop system for hydrate and other flow assurance studies.

As well as this, for over 20 years the Hydrate team at Heriot-Watt have been undertaking specific individual consultancy/technical flow assurance studies for hydrocarbon production and service companies. In light of this, demand has been growing steadily for specialised hydrate studies, training for engineers, and advanced equipment for laboratory studies.

To meet the demand for such services, senior team members of the Centre for Gas Hydrate Research, with support from Heriot-Watt University, founded Hydrafact - Hydrate and Flow Assurance Consulting and Technologies - a Heriot-Watt Spin-out Company.

Early 2000's
Hydrafact officially launched
Hydrafact was officially launched on the 20th April 2006. It now undertakes all commercial activities of the Centre for Gas Hydrate Research and Reservoir Fluids Research Group, with the aim of providing high-quality and competitive technical services to the industry and to commercialise IP developed at the CGHR.
Hydrafact establishes office and laboratory
In December 2009 Hydrafact moved to its own laboratory (including an H2S lab) and office building in the Heriot Watt University Research Park. In addition to its own lab facilities, Hydrafact retains access to the Centre for Gas Hydrate Research's staff and equipment resources, including the C-FAR flow loop.
