This paper presents a study aimed at using simulation modelling in the oil and gas sector. The study analyses the activities of an enterprise in this industry in order to create simulation models based on real data. The results of the analysis are used to develop methods aimed at improving the performance of companies in this sector. This study is a comprehensive literature review, a detailed analysis of the operation of companies and a modelling process to improve their performance. The results of this study enrich the overall knowledge base of the field by expanding our understanding of how simulation-modelling techniques can be applied in the oil and gas industry. This work will be useful in the future when a more detailed study is based on it. Modeling takes place, during which the best concept of system operation is selected. There is a need to create a model of the environment in addition to this type of modelling. #COMESYSO1120.
