Abstract
This research focuses on investigating the melting behavior of crude oil extracted from five specific fields located in Kazakhstan. Understanding the crude oil's melting point and the temperature at which it transitions to a solid state is crucial for predicting wax precipitation, a significant concern during oil transportation and storage. The study employs various laboratory instruments to achieve this goal. These instruments include gas chromatograph for analyzing the oil's composition, differential scanning calorimeter (DSC) for measuring the heat flow associated with phase changes during temperature variations and pour point tester for determining the lowest temperature at which the oil can still flow. By utilizing this comprehensive approach, the researchers aim to establish new correlations between the crude oil's properties and its melting point and solid-state transition temperature. These newly developed correlations are expected to demonstrate a closer alignment with the actual melting points of various hydrocarbon components within the crude oil compared to the standard correlations currently employed by most prediction models. This improved accuracy could lead to more reliable wax precipitation predictions, ultimately benefiting oil production, transportation, and storage operations in Kazakhstan. Obtained experimental results provide valuable insights into the melting properties of the analyzed crude oil samples.This observation indicates that this particular oil is less viscous, as it solidifies at a relatively positive temperature. Furthermore, by incorporating these findings along with the oil's molecular weight, researchers can potentially establish a correlation specific to Field A oil for predicting wax deposition.
