This paper describes a comprehensive solution for the management of technological and economic potential, implemented using a digital information system (IS) - SPecTR, which includes a section of the Unified Register of geological and technical measures with automatic selection and multi-user expertise of geological and technical measures in the production and injection stocks, as well as Well Intervention Efficiency Monitoring section.
A significant advantage of the information system under development is the maximum automation of the entire selection process and subsequent monitoring of success: from the input data needed to calculate, i.e. technological modes of operation of wells, isobar maps, porosity and permeability, initial and residual oil saturated layers, well logging data interpretation results, well coordinates, charts, PVT data, etc., - to to determination of the risks to the performance of light and heavy well interventions for each specific well, calculating incremental oil flow rates and economic viability for the selected well intervention candidates, conducting factor analysis of achieving the planned effect of well interventions, etc.
The described system provides for a unified approach to determining the technological (production) potential for various Gazprom Neft's assets. At the same time, the system can be called flexible since it enables users from various Subsidiaries to "customize" the candidate selection process with account of specifics of their assets: by including additional selection criteria in the selection process, adjusting thresholds, setting well intervention design parameters for calculating the target conditions, etc.
The SPecTR system is currently implemented and has been undergoing commercial operation at 9 Subsidiaries of Gazpromneft.
