Tatneft OAO has developed new improved acidizing compositions referred to as KSK. The paper presents data on composition and physicochemical characteristics thereof, as well as different application scenarios, geotechnical conditions of application, and results of pilot tests. Analysis of commercial application of KSK compositions in Tatneft assets will be discussed in subsequent publications.
Key words: acidizing compositions, well stimulation, reaction rate, acid deviation.
