Calculation and optimization of oil treatment and pumping facilities during project evaluation and reengineering

Abstract

The article discusses the use of different approaches to the calculation of technical and economic parameters of oil and gas treatment and pumping facilities in the evaluation of projects and reengineering. The usual practice of assessing the cost of training facilities at an early stage involves the use of analogous facilities designed for a certain composition and properties of the produced fluid. At the same time, the estimated project according to these indicators may differ significantly, both in quantitative and qualitative indicators. To bring the existing analogue to a comparable form, heuristic approaches are often used, such as correcting scale coefficients, the Lenz (Nelson) formula, etc. As calculations show, these approaches often make significant errors in the evaluation of the project, especially when they are applied to such complex objects as oil and gas treatment facilities. Taking into account the fact that the cost of such objects is often a significant part of the total capital costs of the project, the estimation error can be hundreds of millions and billions of rubles. The paper proposes an alternative approach, as well as a software solution that allows you to get the optimized characteristics of the object and more accurate, the cost of the object, taking into account all the main influencing factors and processes, and thereby improve the accuracy of the project evaluation.
