In the era of global technological changes in oil and gas companies, business processes for extraction, processing and transportation of hydrocarbons are being improved, which requires modern high-tech equipment serving these technological processes. Ensuring trouble-free, uninterrupted operation of the equipment of oil and gas companies requires the introduction of digital technologies for its maintenance and repair. The relevance of this study is to develop digitalization of business processes for equipment reconditioning in oil and gas companies. The main business processes of extraction, transportation and processing of hydrocarbons are digitized quite fully. Supporting business processes of repair and maintenance of the equipment aimed at reconditioning and ensuring its smooth operation require further development based on their digitalization.
