What we do
Rigorous simulation for critical technical decisions
SIMULEX applies expert simulation, modelling and decision support to complex systems where decisions depend on sound engineering judgement, transparent assumptions and reliable technical evidence.
We help partners evaluate system behaviour, compare scenarios, validate assumptions and understand surface-facility interactions before major commitments are made.

Team and Expertise
A founding team built on simulator validation, simulator development and real-field predictive modelling
SIMULEX is led by a founding technical team with deep expertise in chemical engineering, petroleum engineering, physics, computer science, reservoir simulation, numerical modelling and real-field subsurface systems.
The team brings complementary experience across the validation of benchmark reservoir simulation technologies, the development of advanced simulator capabilities, and the construction of complex predictive models from real field and history-match data.
Co-founder and CEO
Chemical Engineer with a PhD in Petroleum Engineering and 15 years of experience across reservoir engineering, reservoir simulation, thermodynamics, phase behaviour, heavy oil, CCS, geothermal systems, hydrogen subsurface applications and integrated surface-subsurface energy systems.
She has specialist experience in the technical and commercial validation of benchmark reservoir simulators, including workflows and capabilities used by reservoir engineers on complex field-development studies.
Her combined formation as a Chemical Engineer and Reservoir Engineer gives her a rare technical position to understand both surface facilities and subsurface systems, and to couple the physics that governs their interaction.
