Ankush Singh

Reservoir and Completions Technical Team Lead

Ankush Singh is a Senior Reservoir and Completions Engineer, as well as a Reservoir and Completions Technical Team Lead at ResFrac, where he provides value to the energy industry by optimizing the development of fracturing and reservoir projects. He is a geoscientist with expertise in geomechanics and over 10 years of academic and industry experience in research, asset development, and operations.

Ankush received his Ph.D. in Geophysics from Stanford University in 2021. His thesis was focused on predicting variations of stress with depth and analyzing its impact on hydraulic fracture propagation and fault slip. He utilized physics-based modeling and machine learning for geomechanical applications in Unconventionals, Enhanced Geothermal Systems (EGS), and induced seismicity. Ankush also received a master’s degree in Geology from Indian Institute of Technology (IIT) Bombay.   

Ankush also worked as a geoscientist at Shell for 6 years at various international locations including India, Russia, and New Zealand. His role was focused on performing geological modeling, uncertainty quantification and value of information analysis for global oil & gas fields. 

Outside of work, Ankush enjoys hiking, geological trips, and cooking. He is also a keen soccer follower and an avid Manchester United fan.

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).
