Reduction of Risks when Transporting Carbon Dioxide to the Injection Site

The need to implement projects for the decarbonization of technological processes is relevant in connection with the international climate agenda. To reduce greenhouse gas emissions, especially in Scope 3, carbon sequestration activities are indispensable, which can be implemented in various ways. Of great interest is the creation and implementation of industrial carbon sequestration technologies that use the existing oil and gas infrastructure, and in addition, allow obtaining additional benefits by increasing oil and gas recovery. The implementation of this technology largely depends on the environmental and economic feasibility of the project, which is influenced by the selected technologies for capturing and cleaning gas from impurities, the length of the pipeline to the field, a reasonable injection technology, an emergency monitoring system, and many other factors. For this reason, scientific and practical research in this direction are of practical importance and are quite relevant. The purpose of our study is aimed at reducing the risks of oil and gas companies in the transportation of carbon dioxide from the place of formation to the place of use when injected into the reservoir to enhance oil or gas recovery. The article presents the results of the analysis of possible emergency situations during the transportation of carbon dioxide to the place of injection. Recommendations are given to prevent them, namely, equipping the route of the pipelines being designed with pressure sensors, justifying the reaction time to stop the compressor equipment, which is no more than 6 minutes and the departure of technical specialists to the emergency facility no earlier than 15 minutes after the incident. It is noted that in order to reduce pipeline corrosion and prevent carbon dioxide leaks, it is recommended to comply with the conditions under which the gas is in a supercritical state, in addition, to purify the gas from impurities in the transported carbon dioxide stream and use a corrosion-resistant material for the manufacture of the pipeline.
