Abstract
The development of reef deposits is complicated by the high variability of the geological and physical properties of the reservoir along strike and section, as well as the variability of the rheological properties of oil within the reservoir. The level of interaction between wells before they are put into production is not predictable. In such conditions, the organization of an effective system of stimulation of the reservoir is associated with the solution of many unique in each case technological problems. Using the example of a group of reef deposits, the experience of introducing exposure systems by various agents and their combinations (water, gas, water-gas) is summarized. It is shown that the exhaustion of natural reservoir energy is not the basis for stopping the development of an isolated section of the reef deposit. It is necessary to assess the primary direction of filtration according to the development history for the formation of a set of measures using the information received (changing the direction of filtration flows, changing or combining displacing agents), including the information for areas consisting of only two wells. The reaction features of producing wells that provide the basis for the use of flow deflect technologies are highlighted.
