Leonardo Cruz

Consulting Engineer

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.

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.

2026 ResFrac Annual Symposium Recap

On June 25, 2026, we got the ResFrac community together both in-person at the ExxonMobil campus in Spring, Texas, and virtually around the globe for our Annual Symposium. With our community growing as fast as it is, the energy in the room was absolutely buzzing. We had a jam-packed day of operator case studies, deep-dive technical sessions, and some incredible geomechanical insights from industry legends.

FracTest – An Online Tool for DFIT Interpretation

This week, we are releasing FracTest, a web-based application for interpretation of diagnostic fracture injection tests (DFITs). FracTest is available at resapps.resfrac.com, alongside our other two ResApps, StageOpt and IntTest. DFITs are small-volume fracture injection tests used to estimate stress, pore pressure, and permeability. These quantities form the foundation of the fracture and reservoir engineering work that we do in ResFrac, and so we view DFIT interpretation as one of the most important parts of our workflow.
