- The author in this paper determined the coefficient of porosity from well log data and carried on a study of core samples using X-ray microtomography and traditional methods. A method was elaborated and later tested for measurement of porosity of samples taken from the production interval of shallow super viscous oil deposits of the Tatarstan?s Republic. Also determination of mineralogical composition and characteristics of the reservoir rock for application to future steam flooding experiments. On the basis of the data obtained, was concluded which of the methods gives the most reliable information on this of the reservoir rock under study.

F_RU2655034C1_20180525.pdf - The settings, scale and geometry of lab facilities to simulate enhanced recovery methods play a significant role in the approximation of underground conditions of oil fields. The reliability more or less of the best replication of these conditions is a question of the reservoir engineer when forecasts are made for cases when enhanced recovery methods are applied. This paper presents the results of two experiments carried on in a steam flooding tube facility adding clay in one of them to assess the influence in temperature growth and production rates and onset times of a highly viscous oil field of the Tatarstan Republic. The results of the runs show that 4% (by weight) of clay content in the porous media has a strong effect on the overall oil recovery, reducing the temperature growth rate in average 73% when steam stimulation methods are used.
