Dr. Diana M. Hernandez Baez

I am co-founder of SIMULEX and co-creator of NZEMS, an integrated modelling and decision-support platform for complex clean-energy and multi-energy systems.

My background combines Chemical Engineering, Reservoir Engineering, advanced reservoir simulation, thermodynamics, phase behaviour, thermal recovery, and subsurface energy systems. I am particularly focused on applying this experience to the New Energies sector, including hydrogen, carbon geological storage, geothermal energy, wind integration, CO₂ enhanced oil recovery, underground hydrogen storage, and integrated multi-energy infrastructure.

At Schlumberger’s Abingdon Technology Centre, where ECLIPSE, INTERSECT/IX, and Petrel reservoir technologies are developed and maintained, I served as a Subject Matter Expert Reservoir Engineer within the reservoir simulators team.

My role focused on the technical and commercial validation of legacy and new simulator workflows, capabilities, and reservoir engineering applications for global reservoir engineering clients. This required specialist-level knowledge of reservoir engineering, reservoir simulation, numerical modelling, field-development workflows, Chemical EOR, and the practical behaviour of benchmark reservoir simulators used worldwide.

My research and technical experience also include thermal cracking modelling and characterisation of heavy oil at Heriot-Watt University, as well as thermodynamics and phase behaviour of complex reservoir fluids through work with TOTAL CSJFT and ECOPETRO-ICP.

I am a member of EPSRC’s Peer Review College, a World Geothermal Congress peer reviewer, and a member of SPE and IChemE.

Through SIMULEX, I am interested in building trusted partnerships with universities, research organisations, public institutions, and energy companies working on the practical delivery of the clean energy transition.
