Leonardo Cruz supports a diverse portfolio of companies across the energy spectrum, providing geomechanical expertise for projects ranging from lithium extraction and CO₂ injection to traditional and unconventional oil and gas operations. By bridging the gap between reservoir geomechanics and engineering, he helps clients navigate complex resource optimization challenges.

Leonardo began his career in 1997 at PDVSA, where he built a strong foundation in drilling operations. He later transitioned into advanced academic research, earning a PhD from the University of Minnesota and completing a postdoctoral fellowship at Stanford University.

This technical background led to roles at GeoMechanics International (GMI) and Baker Hughes, where he focused on wellbore stability and hydraulic fracture challenges. Most recently, Leonardo spent several years at Equinor, applying advanced geomechanical workflows to optimize large-scale global assets. In his work with ResFrac, Leonardo leverages this deep experience to support clients to deploy industry-leading modeling and technology.

When he isn’t solving subsurface puzzles, Leonardo is an avid cyclist. A dedicated age-group racer and social rider, he brings the same discipline, endurance, and competitive spirit from the road to his technical consulting projects.

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?

The influence of well configuration on water loss in Enhanced Geothermal Systems

Recently, ‘water loss’ has been a hot topic of discussion for EGS. Fervo reported that they have been producing only 70% of the fluid volumes that they have been injecting at their Project Red. The FORGE project reported a roughly 10% water loss rate. Because projects will have finite water rights, these results have led to concern that growth of EGS will be limited by excessive water consumption. This is a valid concern, and water availability is a legitimate factor in site-selection and project engineering. However, I believe that the problem has been overstated.
