Egor Dontsov

Chief Scientist

Egor Dontsov is a scientist with over ten years of academic and industrial experience.

Prior to joining ResFrac, Egor worked at W.D. Von Gonten Laboratories, the University of Houston as Assistant Professor in the Department of Civil and Environmental Engineering, and the University of British Columbia as Postdoctoral Research and Teaching Fellow in the Mathematics Department. He earned his Ph.D. degree in Civil Engineering at the University of Minnesota and Bachelor’s degree with honors in Physics at Novosibirsk State University.

Egor’s primary expertise area lies in theoretical and numerical modeling of hydraulic fracturing, proppant transport, and geomechanics. He has written and been exposed to the development of several academic and commercial simulators of hydraulic fracturing, proppant transport, and reservoir flow. Egor served as a reviewer for dozens of journals and several scientific proposals within and outside of the US, invited multiple times to give keynote lectures and seminars, as well as participated in organization of minisymposia at international conferences and workshops. Egor has published over fifty peer reviewed papers and received several awards, including Outstanding Technical Editor Service Award from SPE Journal in 2018, N.G.W. Cook award, as well as Best Dissertation award from University of Minnesota to name a few.

On the personal side, Egor leads an active lifestyle, and has climbed over 100 mountains. Over the last decade, he has also enjoyed cross-country skiing, running, mountain and road biking, hiking, and downhill and backcountry skiing. He has recently moved to triathlons. Within a single year, Egor finished his first ever triathlon – ironman distance, earned All World Athlete status, and qualified for US Triathlon National Championship.

Highlights on propagation from preexisting fractures in ResFrac

The purpose of this blog post is to cover recently developed ResFrac capability that allows investigation of the effect of natural fractures on hydraulic fracture propagation. While this option has always been available for the ‘discrete’ propagation algorithm, now it also has become available for the ‘continuous’ algorithm. There are some noticeable changes compared to the previous implementation and they are covered next.

Understanding fracture morphology

Field scale hydraulic fracture simulations reveal a variety of complex fracture geometries. Very often stress interaction between the fractures leads to very asymmetric fracture growth within a stage. At the same time, for some other cases, all the fractures are more regularly shaped and symmetric. This blog post presents results of numerical simulations and analysis demonstrating how fracture morphology changes versus problem parameters for some fundamental cases. The results can be used to better understand the observed fracture complexity in a field scale simulation or as a guideline to achieve the desired fracture morphology.
