FIELD: oil industry.
SUBSTANCE: invention relates to oil and gas extraction using computer simulation. Disclosed is method of determining plurality of values in field facility, implemented using computer, and includes steps whereat: obtaining data model by computer system, representing manifold and each well shaft, wherein model contains one or more units on said field facility, and units include one or more sets of units, wherein each set contains single unit or a plurality of interconnected units, wherein at least one unit in each set is located in well shaft; obtaining of system of linear algebraic equations by computer system, establishing relationship between said values, presented in equations as variables, wherein said values include pressure for each unit in each set and include values of flow rate, determined by specific flow rates into units or from units, in each set, and for each unit equations contain set from one or more equations with values in unit, wherein for at least one unit in each set of units set of one or more equations contains at least one equation with pressure in unit and one or more values of flow rate in unit; executing of equations system linear conversion by computer system, wherein linear conversion includes linear conversion of equations of each set of equations for exclusion of at least one value of flow rate from at least one equation in each set of equations and wherein linear conversion provides converted system of equations; and solving by computer system of converted system of equations for specified values.
EFFECT: technical result is improvement of operation of deposit.
