In the 90s of the XXth century, the Udmurt Republic began to significantly reduce the volume of seismic exploration due to the completion of the stage of searching for hydrocarbons in large and medium-sized structural traps. Since 2001, the increase in oil reserves has lagged far behind production volumes. One of the possible ways to increase the geological reserves of oil was the search and exploration of small and very small oil deposits. However, traditional methods do not allow effectively and with sufficient accuracy identifying hydrocarbon deposits and conducting their reliable delineation, which leads to the drilling of a large number of «empty» wells. As a solution to the problem, it is proposed to use the technology of low-frequency seismic exploration, in its different variants, which will significantly reduce the time and financial costs for the search, exploration and involvement in the development of oil fields. The use of low-frequency seismic exploration will significantly reduce the number of production wells drilled by laying exploration and exploration wells, taking into account their further conversion to production wells, as well as by drilling wells in areas of intense fracturing and high oil saturation of the productive reservoir. This would significantly reduce the cost of finding and exploration drilling such geological features, which would make their development cost-effective. Also, the proposed technology can be successfully used in the study of already discovered fields to establish the exact oil-water contact of the hydrocarbon deposit and monitor the state of development of the field.

The article presents the forecast schemes of oil and gas potential of structures searched for by low-frequency seismic exploration, and also presents the advantages of using low-frequency seismic exploration for forecasting and monitoring the development of oil fields in the Udmurt Republic.
