IMPROVING THE EFFICIENCY OF CARBONATE RESERVOIR TREATMENT FOR PRODUCTION INTENSIFICATION: A CASE STUDY OF THE GREMIKHINSKOYE FIELD
Annotation. The Bashkirian formation of the Gremikhinskoye field is characterized by carbonate, cavernous-fractured, highly heterogeneous reservoirs. These rocks exhibit a high degree of stratification and serve as reservoirs. Traditional development methods and waterflooding have not yielded the expected results — producing wells are rapidly watered out by both injected and formation water. The reservoir is currently at its third stage of development and is marked by a high watercut level averaging 94%. The dynamics of fluid production closely follow the injection dynamics, which may indicate channeling, water breakthrough to producing wells, and the formation of numerous flooded-out zones during reservoir development.
Under such conditions, a comprehensive treatment of near-wellbore zones is often required in order to engage low-permeability intervals. Conventional acid treatments may worsen the situation by accelerating water breakthrough and increasing oil losses, since the Bashkirian carbonate reservoirs are characterized by highly uneven permeability and porosity. For such geological conditions, a treatment method is needed that ensures uniform impact on the entire near-wellbore zone, including both permeable and low-permeability layers.
Keywords: diverting acid composition, diverters, inflow profile redistribution, acid treatment, blocking of flooded-out intervals.
