Selection of Effective Solvents – Universal Modification of Presently Available Enhanced Oil Recovery Methods and Oil Production Stimulation Processes

In this paper the evolution of the methods of oil production intensification and enhanced oil recovery (EOR) in the USSR and the Russian Federation is considered. By authors were identified and described the historical stages of development of the secondary and tertiary EOR fields on the example of the Republic of Bashkortostan with the indication of major events that have had a significant impact on the technology development of deposits in the country.

A lithofacies model of the Fainsk oil field YUS11 formation was built. The results of interventions for oil production stimulation and enhanced oil recovery depending on the section penetrated by wells were considered. Criteria for selection of various types of interventions in particular geophysical conditions were given, and recommendations on the selection of technologies for bottomhole zone processing (BZP) and enhanced oil recovery (EOR) were made. The research objective is to evaluate the effectiveness of interventions in terms of enhanced oil recovery, adapted to the specific features of the field geologic structure aspects. Through the use of sedimentary deposits facies analysis method, a lithofacies model of the Fainsk oil field YUS11 formation was constructed. The application of field-geologic analysis gave an option to evaluate the technological effectiveness of interventions for oil production stimulation and enhanced oil recovery depending on the reservoir units genesis penetrated by wells.

The article discusses one of the most promising oil recovery methods - sidetracking (sidetracking), explores the development status of formation that use this method, and justifies the selection of candidate wells for its implementation. Based on the example of the Variogan field, the effectiveness of the sidetracking operations was determined depending on the increase in well production. Using the obtained dependence, we can estimate the rate of increase in cumulative oil production.

Recovery Methods

The features of evaluation of the effectiveness of flow deflection technologies of enhanced oil recovery methods. It is shown that the effect of zeroing component intensification of fluid withdrawal leads to an overestimation of the effect of flow deflection technology (PRP). Used in oil companies practice PRP efficiency calculation, which consists in calculating the effect on each production well responsive to subsequent summation effects, leads to the selective taking into account only the positive components of PRP effect. Negative constituents — not taken into account and it brings overestimate over to overstating of efficiency. On actual examples the groundless overstating and understating of efficiency is shown overestimate at calculations on applied in petroleum companies by a calculation.
