APPLICATION OF SELF-DIVERTING ACID COMPOSITIONS FOR OIL PRODUCTION INTENSIFICATION FROM HETEROGENEOUS CARBONATE RESERVOIRS

 

Annotation. In Udmurtia, the majority of oil fields have entered the late stage of development. As the most productive reserves become depleted, more attention is being directed toward reserves associated with heterogeneous carbonate reservoirs, whose pore-space structure is complicated by the heterogeneity of their filtration-capacity properties. A common problem in developing such reservoirs is premature watering of production wells and uneven extraction of reserves across the reservoir section. At high water cut of production wells, the effectiveness of most geological and technical operations, including acid treatments, decreases significantly. The most promising approach is the application of self-diverting acid compositions, which allow for uniform engagement of the entire productive zone of the oil reservoir during treatment, reducing clogging of the bottom-hole zone and enhancing oil production rates.

Keywords: self-diverting acid composition, diverters, inflow profile redistribution, acid treatment, blocking of flooded-out intervals.
