About one method of optimization well interventions list

To maintain oil and gas production at a higher level, a complex of well interventions is usually use in the petroleum exploration. The list of well interventions is formed on the basis of the analysis of the current state of reservoir development, technical condition of wells, economic efficiency and other significant factors. To ensure quality planning of production indicators in the oil company, the list of well interventions is formed for years ahead and includes, sometimes, thousands of activities. Usually for most events, only one year of their performance is pre-set. It is of interest to study the influence of variation of the well intervention's months performing within a year for economic indicators. This article proposes a mathematical formalization of the problem of ordering the list of well interventions taking into account some production and economic conditions. The formulated problem is the problem of nonlinear optimization. To solve the problem, a heuristic method is proposed, a full description of which is given in the article. In conclusion, the results of optimization for one real example are given.
