The article reviewed issue of injection capacity distribution in time for injection wells, as well as production profile of offset wells for spot waterflooding of different development objects of Tuimazinskaya group of fields. Maximum permitted concentration of oil and solids in injection fluid is set. Reviewed efficiency of methods of well injection capacity restoration and established most efficient well treatment technique.

This paper presents integrated analysis of hydraulic fracturing efficiency in residual oil displacement. Enhanced oil recovery methods increase both oil displacement efficiency and sweep efficiency. The authors propose integrated analysis of well flow rates and light absorption coefficient variations to evaluate the effect of fracturing technology on reservoir performance. This paper also presents comparative analysis of well performance and light absorption coefficient variation data. The analysis has been performed for Devonian terrigenous deposits of the Romashkinskoye field.

Foam fracturing technology was successfully tested and Implemented in Surgutneftegas OJSC. Treated wells showed substantially reduced completion times and Increased oil production compared to the adjacent wells, indicating potential efficiency of the technology. In the pilot jobs the guidelines for foam fracturing design and execution were developed. The method of controlling foam properties during the operation was developed and successfully tested.

The article reveals the pattern of extra-viscous oil production on the Ashalchinskoye field by steam gravity recovery method. Effects of specific temperature and pressure conditions on the performance of pumping equipment during extra-viscous oil production are considered. Solutions to decreasing downtime steam losses and extending pumps' run time are suggested.
