Planning the development of gas fields' group taking into account uncertainty of basic data

It is proved a choice of fuzzy sets for strategy generation of development of gas fields' group taking into account uncertainty of basic data. According to approximated andcombinatory method it is offered an approach to implementation the fuzzy extension of simulation and optimization determined problems to development of gas fields' group. Various tasks are considered that arise in the presence of uncertainty in an assessment of gas reserves of various categories.It were presented solutions on effective implementation of System of simulation and optimization of the gas production taking into account uncertainty of basic data.
Materials and methods
Fuzzy mathematics, interval mathematics, simulation models, methods of discrete optimization, computer-aided systems of planning.
Results
Using of fuzzy sets for the accounting of uncertainty basic data in particular gas reserves of various categories is considered during planning the gas fields' group development.
Сonclusions
Fuzzy sets can be successfully appliedto forming a strategy of gas fields' groupdevelopment taking into account uncertainty of basic data, including the various categories gas reserves. For this purpose it is expedient to use a fuzzy enhancing of the determined problems of simulation and optimization thedevelopment of gas fields' group in conditions when objective function and restrictions of optimizing tasks can't be defined analytically. Fuzzy extension can be effectively realized in System of simulation and optimization of the gas production.
