The ever-increasing complication of geotechnical conditions of well jobs makes digital engineering particularly relevant and significant. The final success of digital engineering is defined by two factors: the software level and the input data quality, along with design model verification. The article considers the methodology of digital engineering integration into the production process exemplified by Gazprom podzemremont Urengoy LLC. It describes the modern software packages used in the company and allowing to analyze processes running both within the conventional workover technologies and with using coiled tubing rigs. The focus is on the methodological aspects, namely, developing evaluation techniques for design models’ parameters adequacy, their modification considering workover process specifics, eliminating uncertainties, and subsequent correcting models based on actual well data and continuous cooperation with software package developers. The conclusion shows the scope of processes and the number of tasks resolved since the implementation of digital engineering. It is concluded that having the software packages does not guarantee their successful integration into production without the appropriate methodological and expert approaches, which would create a symbiosis of theory and practice.
