A New Relantioship for the Prediction of the Formation of Gas Hydrate in Fluids Petroleum

Abstract

The presence of gas hydrates in natural gas extraction, transport and storage facilities, creates problems related to the blocking of flow pores in the productive layer, the clogging of pipelines and especially the increase in the delivery and pumping pressure of natural gas. This aspect usually leads to damage to oil structures by damaging them and especially by stopping gas supplies. The present work presents the history of the identification of natural gas hydrates present in nature as well as their nucleation conditions.
 Also, following the laboratory determinations, two new correlations could be made to indicate the pressure and temperature at the beginning of the nucleation of gas hydrates, starting from the determination of their specific gravity.
 The new correlations were compared with the laboratory data and with the existing correlations in the specialized literature, the results being close.
 Also, based on the observations of the formation of gas hydrates of some gases with a specific density between 0.6 and 1.0, it was possible to analyze the laboratory data with those obtained after running a new correlatios.
