Review and applicability assessment of acid treatment methods for bottomhole formation zones of carbonate complex reservoirs of oil and gas fields

The majority of the world and Russian Federation oil deposits are confined to complex carbonate reservoirs. Most carbonate reservoirs feature a complex geological and geophysical structure, the presence of high-capacity caverns, cracks, and pores, high-viscosity oils, as well as hard-to-recover reserves. To control development parameters in such challenging conditions and fulfill oil and gas production targets it is required to use modern enhanced oil recovery technologies. One of the most widely used methods is well acidizing to restore formation permeability. Today, global oil production employs various methods of acid treatment, which differ in their production technology, dependence on the lithological and mineralogical composition of the reservoir, duration, their effect, etc. Each of the methods used has both advantages and disadvantages, which sometimes makes it difficult for oil specialists to choose the right technology for treating the bottomhole formation zone. The present work discusses domestic and international experience in acid treatment of carbonate reservoir wells, in order to identify the advantages and disadvantages of the methods used.
