The article considers the problem of ensuring rational and most efficient subsoil assets use, in particular, pays attention to the problem of high-quality sealing of an oil and gas well annulus. The interrelation of the bodies system covering the most significant relations of subsoil assets use is analyzed, one of the main tasks of which is normative and legal regulation in the field of fuel and energy complex. The main causes of the occurrence of behind-the-column flows and inter-column pressure in wells are specified, and the characteristic of typical complications caused by the violation of the cement stone integrity, which subsequently become the basis for financial and material losses and a threat to environmental safety, is given. The question of updating the problem of poor-quality well cementing is raised before the subsoil assets user and the state. The analysis of the market of technologies able of solving the problem of forecasting losses caused by behind-the-column flows and their calculation is carried out as well as directions for the development of innovative technology within the framework of import substitution for the purpose of providing continuous control and monitoring of production wells are outlined. Conclusions are made and recommendations are given on the measures necessary to stimulate oil and gas producing companies to implement the principles of environmentally-friendly, safe and rational use of subsoil assets.
