Overview

Analysis reveals critical temperature limits for gelled crude oil in cold pipelines, suggesting safety improvements.

Key Points

  • The study found that temperature drop significantly increases the adhesion of gelled crude oil in pipelines.
  • Results showed that an accurate predictive model estimates the minimum adhesion-slip temperature within 2 °C.
  • Using XDLVO theory, the interactions between gelatinous oil particles and pipe walls were systematically analyzed.
  • Identifying safety boundaries can enhance operational efficiency and prevent pipeline issues during shutdowns.
