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.

Recorded ARMA HFC 2023 Series Presentation– Optimization of Perforation Phasing for Improving Uniformity of Proppant Distribution Between Clusters

This ARMA Hydraulic Fracturing Community (HFC) presentation summarizes the work on proppant transport in horizontal perforated wellbores. Specifically, it discusses the model for proppant distribution between perforations depending on their orientation and location within the stage, optimal configurations are proposed, and performance is evaluated.

Optimization of perforation orientation for achieving uniform proppant distribution between clusters

Previously, a mathematical model for the problem of slurry flow in a perforated wellbore was described and the underlying physical mechanisms were discussed. The purpose of this blog post, on the other hand, is to couple the model with an optimization algorithm to investigate optimal perforation orientations that lead to the desired uniform proppant distribution between perforations. A brief description of the model is added at the beginning to cater for readers who are not familiar with the previous blog post.

Proppant distribution between perforation clusters

This blog post summarizes the model for calculating proppant distribution between perforation clusters. A very detailed description of the model and literature review are available in [1]. The purpose here is to outline the model and its main features, to demonstrate the comparison with some of the available data (more comparisons in [1]), as well as to discuss limiting cases and sensitivities to various parameters. This blog post is solely focused on presenting the mathematical model. In future work, the results will be applied to practical optimization decisions.
