Statistical model employment in calendar time of the producing well stock analysis

Wells during their operation require periodic shutdowns for repair work and well interventions in order to intensify oil and gas influx. In the analysis of the producing well stock utilization over time, the downtime of the wells is of great interest, as it characterizes the intensity of their employment (expressed by the operating factor), the total volume of oil production and losses in oil production. Effective oil production management is based on reliable information support, however, the existing extracted products accounting system leads to a distortion of real losses and the inability to accurately determine their actual value [1]. The value of economic and mathematical methods is extremely great when choosing the best option for economic problems solving. Most planning tasks are usually multivariate. The search for the most effective solution by direct enumeration of all possible options requires enormous labour costs, and this sometimes is practically impossible. [2]. To solve this problem, it is proposed to apply a statistical model to determine oil losses due to various well downtimes. Using the developed recommendations in production provides the ability to fully account for all losses arising from oil production.
