MohammedMohammed A Almobarky is a PhD student in Harold Vance Department of Petroleum Engineering at Texas A&M University. He holds a B.Sc. and M.Sc. degrees in Petroleum Engineering from King Saud University, Saudi Arabia. Mohammed is a lecturer in the Petroleum and Natural Gas Engineering Department in King Saud University in Saudi Arabia since 2004. He has been involved in teaching several petroleum engineering courses as a teaching assistant before he was obtained scholarship for PhD in Texas A&M University. Moreover, he has been a part of several internships with the Arabian Drilling Company, affiliated with Schlumberger (Dhahran, Saudi Arabia), and Research & Development Center in Saudi Aramco (Dhahran, Saudi Arabia). His research interests focuses on EOR by miscible CO2 flooding and Mobility Control using foam flooding. Currently, Mohammed is investigating several foaming agents (i.e. surfactants) to enhance their ability to generate more stable and stronger in-situ foam in absence and presence of crude oil. Mohammed is familiar with Slimtube MMP experiment, core flood experiment, IFT measurements, zeta potential testing, gas mobility, and viscosity.

 

SergeySergey Parsegov focuses his research in hydraulic fracturing, including geomechanical problems of hydraulic fracture initiation and propagation through naturally fractured reservoirs. He obtained his MSc degree in Petroleum Engineering and BSc (both with honors) from Moscow Institute of Physics and Technology, Russia. He is responsible for experimental part of Crisman Institute for Petroleum Research project 2.5.25. He conducts: Rock mechanics lab experiments; Energy Dispersive Spectroscopy (EDS) on the SEM measurements and Computer tomography (CT) and micro-CT scanning of cores.

Sergey started his career as reservoir engineer and petroleum economics analyst at LUKOIL (LON: LKOH). After working in petroleum companies he moved on to investment analysis of petroleum exploration and production projects. He became Chartered Financial Analyst (CFA) charterholder in 2010. Prior to beginning the PhD program Sergey leaded consulting projects, including project management solutions implementation in Gazpromneft (LSE: GAZ).

 

SangyupSangyup Lee is a Graduate Research Assistant and Ph.D. student at Texas A&M University in Petroleum Engineering. He holds a B.S. degree in Civil Engineering and a M.S. degree in Geotechnical Engineering from Korea University, South Korea. Sangyup had an internships with Chevron (Bakersfield, CA, USA). His research focuses on developing the equivalent permeability estimation code and developing the iteratively coupled fluid flow and geomechanics using fractal and statistical methods. He calculates the equivalent directional permeability distribution of discrete fracture map data and reflects the heterogeneous characteristics of fracture geometry in permeability calculation. He estimates the interaction effect between fluid flow and geomechanics on production performance through coupling simulations and calculates sensitivity of property effect on the production performance through sensitivity studies. His internship project was also related to development of coupled simulation model: Investigate the Mechanism of Subsidence of Diatomite Reservoir in Lost Hills (LH) using Fully Coupled GMRS (Geomechanical Reservoir Simulator).
