... Abstract There is a discontinuity in the tabulated thermodynamic properties as the fluid is going across the critical point. In this paper, utilizing regularization techniques, correlations are established to continuously determine fluid properties during the transition through the critical...

... Abstract Gas hydrates are a major flow assurance problem in the oil & gas industry. If not treated well, they pose a major threat to pipeline failure. In this work, a simple statistical correlation is developed for the prediction of gas hydrate formation temperature. For this, initially...

Finally, the predictive abilities of the best model are further validated by comparing its performance with well-established mechanistic models based on empirical correlations. The Random Forest...
