Effective process of development of hard-to-recover reserves, including tight and low permeable reservoirs of Domanic deposits, is impossible without a complex approach, connected with the laboratory study of core samples by specialized methods coupled with well log data and with preliminary modeling of stimulation processes as wells as new methods of field development. Adequate selection of technologies for the development and stimulation of the seams is also based on the study of the characteristics of the fluids of house deposits. The studies are aimed at improving the drainage of oil in the rocks in terms of increasing the production rate of the wells of the Bavlinskoye field. In the study of the concentration of hydrocarbon components in the composition of the oil samples of the house deposits on the wells, it was noted that with increasing molecular weight of the hydrocarbon component, the concentration of normal alkanes in the total composition decreases. According to the performed quantitative analysis of GLC, it was concluded that the dynamics of the change in the component composition of the oil of the wells under study by concentration does not undergo significant changes in the extraction process. In the study of rheological characteristics, the homogeneity of the properties of oil was noted for them and new information was obtained on the anomalous viscous properties of the oil under study. The revealed dependencies are proposed to be used to improve available and create new technologies for effective development of house deposits. The results of monitoring are provided with the use of services of a number of service companies for the development of cracks after a multi-zone fracturing at one of the wells, taking into account the direction of the development of anomalies and fractures, according to which the cause of the watering of the well is established. It is shown that the development of unconventional deposits for the region - dense, weak permeable carbonate reservoirs requires considerable material investments and intellectual resources. However, effective work with the hardy breeds today, as well as with other categories of hard-to-recover reserves, is the basis for the stability of the oil industry in the future.
