description: This paper presents a study of the applicability and the first results of pilot works of the technology of periodic water injection into production wells with subsequent oil production (Huff and Puff), which was not previously used in Russia. The physical principles of capillary impregnation in a hydrophilic reservoir were presented, which, under given conditions, should lead to an increase in oil production in waterless wells during cyclic water injection and shutdown with subsequent production. Since this technology was not previously used in Russia, a review and analysis of the unsuccessful application in the United States and the successful experience in China in fields with similar properties and wells was carried out. The Priobskoye oil field with a terrigenous reservoir of low permeability is considered. Preconditions for application on the selected field from the development history and geological and physical characteristics are given. It is planned to use the technology at marginal waterless wells with hydraulic fracturing, which are on the verge of profitability, to increase oil production. For the design of pilot works, calculations were made on a synthetic hydrodynamic model with double porosity and permeability, according to which a significant increase in oil production in a marginal well was obtained relative to standard operation. Pilot work was carried out on four oil wells of the company's field, which were previously planned to be transferred to the reservoir pressure maintenance stock. Only two of them managed to meet the required injection and shutdown periods. Thus, the first in Russia experience of using the technology of cyclic water injection into a production well with subsequent withdrawal was obtained. Based on the results of the analysis of the pilot work carried out, conclusions are drawn about the successful initiation of capillary impregnation in the reservoir of the Priobskoye field and the need to carry out the following pilot work with more efficient technological modes.
