ImageStrat was founded in 2018 to provide specialist consulting services to the energy sector.

We're based in Perth, Western Australia. We can QC, process and interpret a wide variety of borehole images, and add value by working closely with you, and your consultants, to maximise the value of your data.

The Team


Andy Wilson BA (hons) MSci PhD

Director | Sedimentologist | Stratigrapher | Image log specialist

Andy holds BA (Hons), MSci and PhD degrees in Geological Sciences from the University of Cambridge, UK. In 2009 Andy joined the Stratigraphy research group at Liverpool University as a research scientist studying the stratigraphic architecture and sedimentology of the fluvial Beaufort Group in the Karoo Basin of South Africa. Andy co-wrote a field school in fluvial sedimentology and stratigraphy based on his field research which he co-led on three occasions with colleagues from Manchester University and Chevron Australia. In 2013 Andy moved to Australia working for Chemostrat as Geological and General Manager, Task Fronterra Geosciences as a Senior Sedimentologist/Senior Geologist working on borehole image interpretation, and MGPalaeo as a Sedimentologist and Borehole Image Interpreter. Andy has worked on subsurface projects from basins in Australia, PNG, Timor-Leste, New Zealand, Mongolia, USA, and China, and has extensive fieldwork experience studying outcrops and surface processes in Iceland, Taiwan, South Africa, New Zealand, Switzerland, Spain, Greece and Italy, among other places. He has also co-authored a number of peer-reviewed papers in premier journals, and maintains a strong interest in all depositional processes, environments, and landforms. Andy fellow of the International Association of Sedimentologists, Member of the Petroleum Exploration Society of Australia, lifetime Fellow of the Cambridge Philosophical Society, Associate Fellow of the Higher Education Academy, and Member of the Geological Society of Australia. Andy is also an Adjunct Senior Research Fellow at Curtin University in Perth, Australia.

Irene Wallis BA/BSc (hons) MSc PhD

Principal Geologist, Cubic Earth | Geothermal Geoscience | Borehole Images | Geomechanics

Irene Wallis is a geothermal consultant, now specialising in borehole image analysis and geomechanics. Since transitioning from mining to geothermal in 2009, she has accumulated 15 years’ experience in the exploration, development, and operation of medium- and high-temperature resources. She has worked on geothermal projects New Zealand, Chile, USA, Djibouti, Indonesia, and the Philippines and has broad, interdisciplinary experience that includes geology, drilling, reservoir engineering, and geochemistry. Her recently submitted doctoral thesis explores the geologic controls on geothermal fluid flux from the sub-meter to kilometre scale. Ms Wallis teaches scientific Python, while also maintaining open-source projects and consulting in that sphere.
