Eric Mackay holds the Energi Simulation Chair in CCUS and Reactive Flow Simulation in the Institute of GeoEnergy Engineering at Heriot-Watt University, where he has worked since 1990. His research interests include the study of fluid flow in porous media, such as the flow of oil, gas and water in subsurface geological formations. He has over 100 publications related primarily to maintaining oil production when faced with mineral scale deposition, but since 2005 he has also worked on Carbon Capture and Storage. He is involved in projects identifying methods for calculating secure CO2 storage potential in saline formations and depleted hydrocarbon reservoirs. As well as his research interests, Eric is involved in extensive consultancy activities, he delivers short courses for the oil industry and is a technical editor for a number of journals. He has also taught Reservoir Simulation to the residential and distance learning MSc classes at Heriot-Watt University since 1990. Eric holds a BSc in Physics from the University of Edinburgh and a PhD in Petroleum Engineering from Heriot-Watt University.
