Research Output per year
From 1977 to 1980 I was at the Centre for Tectonophysics, Texas A&M University (experimental rock mechanics, fracture systems, upper crustal deformation). This was followed by 10 years in the US oil and gas industry (management of structurally complex fractured reservoirs, simulation of their flow). A return to academia (1991 to 1998) produced a PhD in Basin Development and Basin-scale Flow Systems at Glasgow University concurrent with and followed by a fixed-term research contact (flow in deforming fractured media) joint between Geology and Civil Engineering. I have been at Heriot-Watt University for 17 years. This time includes several years as Director of the Petroleum Geoscience MSc but has mostly been focused on Geomechanics and Geomaterials research encompassing topics from Structural Geology to Nanomaterials Science and Full Field Rock Mechanics laboratory testing to subsurface fractured and fracture-induced reservoir issues. My current research focus is 2-fold: linked geomechanics and flow in developing geological structures at the cm to the reservoir scale; and laboratory-based rock and flow system testing, particularly with embedded sensor systems.
Current main areas:
MechSeis 2011-18. Identification and prediction of evolved petrophysical and acoustic properties in deformed carbonate rocks via rock mechanics testing and geomechanical simulation.
Bots in Rocks 2014 -17 (with Dr Flynn). Development and use of nanosensors in deforming rocks for evolving rock and fluid property identification: a non-destructive laboratory study of rock deformation and fluid movement. Experimental investigation of reservoir rock deformation using sensors for direct measurement (Bots in Rocks 2)
Deformation band development in sands and sandstones 2015-2019 (with Dr Charalampidou) Quantitative assessment and experimental replication of deformation band development in partially consolidated natural sands and sandstones. A collaborative project with Universitie de Grenoble.
Numerical Diagenesis (with Drs Buckman and Jiang). Characterisation via high resolution methods of diagenesis in clastics and its digital representatation via pore architecture reprentations.
