This paper presents a probabilistic electrical submersible pump selection methodology for conditions of high parameter uncertainty following geological and technical operations. The primary challenge is significant variability in productivity index during the post-workover period, which critically affects pump operating regimes. Wells with high gas-oil ratios present particular complexity, where the pump's ability to handle gas-liquid mixtures becomes the dominant factor in operational reliability. The research methodology is based on Monte Carlo simulation combined with hydrodynamic modeling in Unifloc VBA, using Standing correlations for PVT properties, Ansari and Beggs-Brill models for multiphase flow calculations accounting for hydrodynamic and thermal effects, and Marquez correlation for natural gas separation at pump intake. A comprehensive efficiency criterion was developed that integrates pump efficiency, energy performance indicators, mean time between failures, and production shortfall risks through normalized coefficients. Testing of the methodology on a Western Siberian mature oilfield demonstrated that small standard deviations in reservoir pressure and productivity index lead to substantial scatter in predicted flow rates, significantly affecting pump sizing selection. It is shown that reducing uncertainty in input parameters through field measurements such as well testing, production logging, or reservoir sampling substantially impacts equipment selection results, emphasizing the necessity for accurate data collection during design and well monitoring phases.
