History
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.

Andy Wilson BA (hons) MSci PhD
Director | Sedimentologist | Stratigrapher | Image log specialist
Geologist with a BA (Hons), MSci, and PhD from the University of Cambridge, UK, and over 21 years of global experience in sedimentology, stratigraphy, geomorphology and subsurface interpretation. I began my career in academia with the Stratigraphy Research Group at the University of Liverpool, studying the fluvial Beaufort Group in South Africa and co-leading field schools with Manchester University and industry partners. I have extensive field experience in places like Iceland, Taiwan, South Africa, Australia, New Zealand, Switzerland, Spain, Greece, and Italy
Since moving to Australia in 2013, I’ve held senior roles at Chemostrat, Task Fronterra Geosciences, and MGPalaeo, working on borehole image interpretation and basin analysis across Australia, PNG, Timor-Leste, New Zealand, Mongolia, the US, and China.
I’m an Adjunct Senior Research Fellow at Curtin University and an active member of several professional societies, including the IAS, PESA, and GSA. My work is published in leading journals, and I remain deeply interested in all aspects of depositional systems and geological processes.

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.
