A 3-step reaction model for numerical simulation of in-situ combustion

Rojas A.A.; Yuan C.; Emelianov D.A.; Saifullin E.R.; Mehrabi-Kalajahi S.; Varfolomeev M.A.; Sudakov V.A.; Lotfullin B.R.; Shevchenko D.V.; Ganiev B.G.; Lutfullin A.A.; Zaripov A.T. (2021)

In-situ combustion (ISC) is an effective thermal enhanced oil recovery method. However, it is still not widely implemented in oilfields. One of the factors limiting the wide application of ISC is the challenge in its ...
Effect of copper stearate as catalysts on the performance of in-situ combustion process for heavy oil recovery and upgrading

Varfolomeev M.A.; Yuan C.; Bolotov A.V.; Minkhanov I.F.; Mehrabi-Kalajahi S.; Saifullin E.R.; Marvanov M.M.; Baygildin E.R.; Sabiryanov R.M.; Rojas A.; Emelianov D.A.; Al-Muntaser A.A.; Ganiev B.G.; Zaripov A.T.; Beregovoi A.N.; Shaihutdinov D.K. (2021)

Using copper stearate as catalysts, catalytic in-situ combustion (ISC) of heavy oil was studied by porous medium thermo-effect cell (PMTEC) and combustion tube experiments. Significant acceleration of combustion was observed ...
Laboratory studies for design of a foam pilot for reducing gas channeling from gas cap in production well in messoyakhskoye field

Saifullin E.R.; Yuan C.; Zvada M.V.; Varfolomeev M.A.; Shanbosinova S.K.; Zharkov D.A.; Nazarychev S.A.; Malakhov A.O.; Sagirov R.N. (2021)

Messoyakhskoye field, operated by Gazprom Neft, is currently experiencing gas channeling from gas cap in production wells because of strong heterogeneity. Foam for a long has been considered as a good candidate for gas ...
Low-temperature combustion characteristics of heavy oils by a self-designed porous medium thermo-effect cell

Zhao S.; Pu W.; Varfolomeev M.A.; Yuan C.; Mehrabi-Kalajahi S.S.; Saifullin E.R.; Sadikov K.; Talipov S. (2020)

© 2020 Elsevier B.V. The combustion characteristics of two Xinjiang heavy oils were studied by the self-designed porous medium thermo-effect cell (PMTEC) that can monitor the temperature alterations caused by oxidation/combustion ...
Nonylphenol ethoxylate surfactants modified by carboxyl groups for foam EOR at high-salinity conditions

Saifullin E.R.; Zhanbossynova S.; Zharkov D.A.; Pavelyev R.S.; Yuan C.; Varfolomeev M.A.; Mirzakimov U.Z.; Ivanov S.Y.; Sitnov S.A. (2021)

High mineralization of water complicates the use of foam in reservoir conditions. Anionic– nonionic surfactants are one of the best candidates for these conditions since they have both high surface activity and salt ...
Petroleum coke combustion in fixed fluidized bed mode in the presence of metal catalysts

Saifullin E.R.; Sadikov K.G.; Varfolomeev M.A.; Emelianov D.A.; Rodionov N.O. (2020)

© 2020 American Chemical Society Petroleum coke is one of the waste products generated in the oil refining industry that can be used as fuel in energetics. However, the low volatile matter content and graphite-like structure ...
Study of the efficiency of gel and polymer-stabilized foam systems for gas shut-off in horizontal wells

Zvada M.V.; Belovus P.N.; Sergeev E.I.; Glavnov N.G.; Varfolomeev M.A.; Saifullin E.R. (2021)

This article describes the assessment of effectiveness of gel and foaming agents for gas shut-off treatments in horizontal wells. The research is carried out through the implementation of a complex of special laboratory ...
