| Abstract: | Highlights: [•] An extended model for pH prediction in oil and gas environments under high pressure and high temperature is proposed. [•] The model takes into account gas fugacities calculated using Soreide and Whitson model. [•] The activity of components in the liquid phase is calculated with Pitzer’s model. [•] The model shows a good agreement with experimental data. [Copyright &y& Elsevier] |
