Research into phase transformations in reservoir systems models in the presence of thermodynamic hydrate formation inhibitors of high concentration

Gas hydrates have been and still remain a difficult problem in the oil and gas industry, solution of which requires considerable efforts and resources. In this work, the mechanism of phase transformations at negative temperatures in the formation of the solid phase is preliminarily studied using the...

The result of such solid phase structure formation is its increased stability in nonequilibrium conditions for a relatively long period of time.https://www.e3s-conferences.org/articles/e3sconf/pdf/2021/06/e3sconf_ght2020_01014.pdf
