Senior Research Scientist

[email protected]

Munhong (Robin) Hui is a senior reservoir modeling and simulation expert with more than 20 years of experience developing and deploying advanced subsurface technologies for complex carbonate and unconventional reservoirs.

Robin joined ResFrac after a long tenure at Chevron, where he served as a Senior Research Scientist and Product Owner, leading the development of upscaling, reservoir simulation, history-matching, and optimization workflows used to support critical asset decisions.

Robin’s work focuses on physics-based and data-driven modeling of fluid flow in fractured reservoirs, including coupled flow–geomechanics. He has made significant contributions to discrete fracture modeling and data–physics hybrid approaches, authoring numerous peer-reviewed publications in these areas. His work bridges fundamental research and practical deployment, with an emphasis on scalable, production-ready solutions.

Robin is an active member of the Society of Petroleum Engineers (SPE), where he serves on a local Section Board and multiple Conference Technical Program Committees. He has received an SPE Regional Award in Reservoir Description & Dynamics and has served on the U.S. Department of Energy’s Methane Hydrate Advisory Committee. He also holds several patents related to reservoir modeling and simulation technologies.

He holds a Ph.D. in Petroleum Engineering from Stanford University and a B.S. in Chemical Engineering from the National University of Singapore.

Outside of work, Robin enjoys playing tennis, hiking, biking, cooking, and gardening.

Targeting the reserves between clusters: modeling strategic refracs and infills in ResFrac

Older, wide-spacing Delaware Basin wells can leave high-pressure rock stranded between fractures. Devon used ResFrac to design liner refracs whose peak rates came in within 1% of forecast, and to show why an offset infill beats a refrac at tight cluster spacing.

Automatic Report Generation in ResFracPro

This month’s release has a feature that I am particularly excited about – automatic report generation. The reports are generated automatically when a simulation finishes. Also, reports can be generated on-demand for simulations that have already been completed. The reports are highly customizable, allowing the user to generate different line plots, 3D visualizations, preview plots, and tabular data. The user can provide a template PPT, so that the report is made with their preferred PPT style.

Introducing ResFrac’s New Multisector Capability

This month’s ResFrac release has a ton of new capabilities. The most important is called ‘multisector’ – the ability to split different sections of the well across different computers. This capability provides a computationally efficient and practical way to run larger models and handle complex scenarios. Hats off to Danial Zeinabady and Michael Nole, who have been the main developers on this project. Beyond them, it’s been a big team effort, pulling in folks from cloud, simulator, and user-success. First, let’s review – what is sector modeling? Why do we need a ‘multi’ version of it?
