METHOD (VERSIONS), SYSTEM (VERSIONS) AND MACHINE-READABLE MEDIUM (VERSIONS) FOR EXECUTION OF OPERATIONS OF SUPPORTING GAS DISTRIBUTION IN OIL FIELD Russian patent published in 2013 - IPC E21B43/16 

FIELD: oil and gas industry.

SUBSTANCE: method includes stages, when supporting gas is optimally distributed according to at least one restriction selected from the group consisting of a restriction for full supporting gas and restriction by full quantity of produced gas for generation of supporting gas distribution. Besides, at the stage of distribution, supporting gas is distributed among multiple gas lift wells in a network for maximisation of liquid/oil flow rate at a drain, besides, at the stage of distribution they apply an autonomous/operative procedure of optimisation, within which data of lift efficiency curve is extracted, the autonomous procedure is solved for optimal distribution to determine optimal distribution of supporting gas, actual network task is solved, which includes many gas lift wells, using optimal distribution of supporting gas to produce updated pressures at the wellhead for many gas lift wells, and the autonomous procedure of optimal distribution is repeated using updated pressures at the wellhead.

EFFECT: modelling and realisation of gas lift operations on the basis of comprehensive analysis of various parameters that impact operations in an oil field.
