At the current stage of development of the oil and gas industry in the world, the processing and utilization of carbon dioxide at the fi eld itself is of interest, which makes it possible to save energy resources during its capture and injection into the well space, which is important for Russia due to the remoteness of the main part of the fi elds. Due to the release of associated gases, in particular, hydrogen, there is a possibility to generate additional energy for own needs at the fi eld and, in addition, to minimize greenhouse gas emissions. It is noted that supercritical fl uid carbon dioxide has a list of advantages, including the absence of toxicity, fi re, explosion hazard, as well as low cost and availability and serves as an environmentally safe solvent. To the technological equipment of surface and underground placement for injection of fl uid carbon dioxide can be attributed the system of its capture, purifi cation, storage tanks, compressor and / or pumping stations. The article recommends rational ways to increase the effi ciency of carbon dioxide capture and injection of carbon dioxide into the well space, as well as the choice of hardware for these purposes, based on a systematic analysis of literature data, staged pilot series and industrial testing of options for solving these problems. Realization of the gas method of oil production growth will lead to several-fold increase in production. The recommended technology will make it possible to improve environmental safety by isolating the emission of CO2 emitted in the oil industry. From the economic point of view the low cost of carbon dioxide, its recycling, possibility of realization at any stage of fi eld operation, high quality parameters of marketable oil feedstock are attractive.
