Elizaveta Gordeliy is a scientist with over ten years of academic and industrial experience in the geomechanics field.

Prior to joining ResFrac, Elizaveta worked as a Research Engineer at École Polytechnique (France), where she worked on the modeling of salt caverns used for hydrogen storage. Before that, Elizaveta worked in several research positions, where she developed numerical models for fractures, faults, and hydraulic fracture propagation: in the Department of Geosciences at École Normale Supérieure (France) as a postdoctoral researcher, in Schlumberger-Doll Research Center as a Visiting Scientist and a Research Scientist, in the Department of Mathematics at the University of British Columbia as a Postdoctoral Research and Teaching Fellow, and in the Civil Engineering Department at the University of Minnesota as a Postdoctoral Research Associate.

Elizaveta earned her Ph.D. degree in Civil Engineering at the University of Minnesota and an M.S. cum laude in Applied Mathematics at the Lomonosov Moscow State University.

In her free time, Elizaveta enjoys spending time with her kids, reading science news, and traveling.

Interesting Papers from the 2026 SPE Hydraulic Fracturing Technology Conference (HFTC)

The 2026 HFTC included 50+ technical paper presentations, a special session highlighting papers from the American Rock Mechanics Association (ARMA), and a dynamic opening session featuring the Secretary of Energy, Chris Wright, and a diverse panel discussion with representatives from Chevron, Exxon, US Department of Energy, and Colorado School of Mines.

Production impact of horizontal fractures

At the 2025 SPE International Hydraulic Fracturing Technology Conference, we (Dontsov, Zoback, McClure, and Fowler) presented “Hydraulic Fracture Propagation Along Bedding Planes Might Be More Prevalent Than We Think” (SPE-226637). The paper reviewed case studies with evidence of horizontal or bedding plane fractures from microseismic, fiber optics, core observations, and casing deformation.

Testing the new Kryvenko model for proppant washout

What controls proppant placement during hydraulic fracturing? As described in Chapter 8 from McClure et al. (2025), ResFrac incorporates a variety of physical processes – viscous drag, gravitational settling, hindered settling, clustered settling, bed slumping, and more. In addition, ResFrac accounts for the complex physics associated with proppant flowing out of the wellbore (Dontsov, 2023; Ponners et al., 2025).
