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.

The Leadership Team
Andy Wilson BA (hons) MSci PhD
Director | Sedimentologist | Stratigrapher | Image log specialist
I graduated from the University of Cambridge (UK) in 2005 with BA (Hons) and MSci degrees in Natural Sciences, specialising in Geology, and completed a PhD in geology, also at Cambridge, in 2009. Since that time I've been working in academia and industry on projects in sedimentology, stratigraphy, geomorphology and subsurface interpretation.
I've always believed that studying rocks in the field is important to understanding the subsurface and have dedicated a large amount of time to study outcrops in Iceland, Taiwan, South Africa, Australia, New Zealand, Switzerland, Spain, Greece, and Italy, among other places.
Since moving to Australia in 2013, I’ve held senior roles in several service companies, 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.

Key collaborators
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.
