Dr. Andrew Madyarov is the Geomechanics Adviser Engineer at TEVERRA. Andrew received his bachelor’s and master’s degrees in mathematics from Novosibirsk State University, working on modeling processes in a catalytic reactor. Then he obtained his Ph.D. in Civil Engineering (Geomechanics) from the University of Minnesota. His thesis was focused on wave propagation and inverse scattering problems in layered media. After graduation, he joined Shell in Houston as a Geomechanics Specialist for almost 10 years, starting with research on in-situ upgrading and conversion processes driven by electric heaters in wells and then moving to hydraulic fracturing of unconventional resources. Andrew then worked with Reveal Energy on hydraulic fracture monitoring with offset well pressure, with TMK IPSCO on well-casing and premium threaded connections design, and with CNPC USA on hydraulic fracturing lab tests on large blocks. Since November 2021, Andrew has been working for TEVERRA on casing deformation, drill-bit vibrations, and other consulting and technology development projects.
