Analysis and development of proposals to improve the equipment and technologies of capture and injection of carbon dioxide at the oil fields

Abstract

This article comprehensive analyzes the techniques and technologies of carbon dioxide capture and injection at an oil field, and also developed proposals for improving the technological process from the beginning of carbon dioxide capture to its injection into the oil reservoir. As a result, the above-ground and underground equipment was analyzed which makes it possible to comprehensively consider the issue of developing oil fields for pumping carbon dioxide in order to increase oil recovery. It is noted that the technological scheme of the field development should include the stage of carbon dioxide capture and processing in order to reduce the cost of its transportation, and by obtaining associated gases, for example hydrogen, to obtain energy for the needs of the field, which is especially important for geographically remote oil fields. The borehole equipment is proposed and the criteria for its operation are justified to control the state of supercritical carbon dioxide at the bottom of the well.
