... homogeneity test of total petroleum hydrocarbons (TPH). The TPH coefficient of variation was evaluated in triplicate samples of 18,75 mL.kg-1dw and 300,0 mL.kg-1dw concentrations of the SBM tests. The TPH coefficient of variation of three tests with reference olefin in triplicate samples of 0.1 and g.kg-1dw...

... DWSIM software tool performance. The overall heat transfer coefficient was determined before continuing with the numerical modeling due to its importance and influence in the CFD simulation, which covers three stages: selection of the most optimum pipeline model, mesh refining, and validation...

... coefficient of salt rocks is five times greater than that of carbonates. This result suggests that creeping in the salt relieves thermal stress induced by cooling. Thus, saline caprock integrity is not influenced by cold fluid injection in the reservoir, as long as salt creeping can be considered. Although...
