Abstract Precipitation of deposited wax on pipe walls is one of the complex flow assurance problems that cause a decrease and complete blockage of oil production rates by reducing the cross‐sectional area of the flow in the pipelines. In addition, surface facilities require higher energy consumption and equipment failure due to paraffin plugs. The purpose of the research is to use the assessment of melting properties in the model of multisolid (MS) forecasting of paraffin in Kazakhstani oil. This article presents the calculation and modification of the fusion properties for a certain Kazakhstani oil for the subsequent calculation of the MS model for predicting wax deposition; numerous approaches have been developed to predict and prevent the flow assurance problems in both science and industry. Most of them are based on predicting the temperature of crystallization of paraffin considering the temperature dependence of the solubility parameters of individual components in the liquid and solid phases, as well as the molar volumes of individual components. Wax deposition can occur anywhere from a reservoir to surface facilities and pipelines. One of the main limitations of the existing models is their applicability to a wide range of crude oil types, while this modified paraffin predicting model will target Kazakhstani crude oil.
