Annotation:
At the present stage of the development of the oil and gas industry of the Republic of Niger, there is a lack of information on the PVT properties of reservoir fluids. This article presents the results of a comparative study of the effectiveness of various correlation equations for predicting certain PVT properties of the Agadem oil field. The possibilities of the Standing, Eye and Vasquez equations for calculating saturation pressure and gas content coefficient are analyzed. The authors of the article propose a modified Glazo equation, and also obtain new equations based on machine learning. It is shown that the proposed equations show better convergence with the results of the laboratory studies of deep oil samples.
