Management of development and conservation of oil and gas fields

Abstract

The purpose of the work is to develop a methodology for managing the development and conservation of fields of field gas-oil pipelines. The analysis showed that the solution of this problem is not paid attention, both on the part of designers and specialists in the automation of design solutions. Although this is one of the most important design problems, on the solution of which the rationality of capital investments depends, the optimality of subsequent periods of operation. Traditionally, this operation is performed manually. The designer, using his experience and intuition, outlines several alternative options, which are then evaluated automatically, including for reliability, hydraulic stability and operational controllability (for example, using the OLGA software package). Methods. For optimal control of these processes, a methodology for indicative and adaptive management of the development and conservation of the field is proposed, which allows taking into account the uncertainties that arise in the future stages of the field operation. At each stage of this technique, it is proposed to carry out a comprehensive optimization of the main field pipelines and use the technique of redundant design schemes with the solution of circuit-structural and circuit-parametric optimization problems, including the stages of conservation of deposits. The numerical experiments carried out have confirmed the high computational and economic efficiency of the proposed approach and method. Conclusions. The proposed method and its software implementation are an effective computational tool for justifying the route and parameters at all stages of management of the development and conservation of field gas-oil pipelines and is recommended for use in the practice of designing the corresponding pipeline systems.
