Abstract
In international field development practice, the most common method of stimulating production from carbonate reservoirs is acidizing. Wells-candidates for geological and technical measures must meet certain criteria of technology applicability, which often necessitates repeated operations on the producing fund during the period of operation. Using the example of carbonate deposits in the Perm region fields the paper investigates the effect of the frequency of acid stimulation on its efficiency based on the analysis of changes in the technological parameters of wells and reservoir properties. It was found that repeated acid treatments are characterized by lower complexefficiency than primary ones. Based on the results of the analysis, a matrix was compiled, which allows for an express assessment of the prospects of acid treatment, considering its frequency and expected technological solutions.
