METHOD FOR GAS FIELD DEVELOPMENT AT THE FINAL STAGE Russian patent published in 2023 - IPC E21B43/17 

FIELD: gas industry.

SUBSTANCE: invention relates to a method for the development of a gas field at the final stage. The method includes the use of modular compressor units with their connection to clusters, groups of gas wells and pipelines of the infield gas gathering system and regulation of the volumes of the extracted gas. Gas is supplied from some existing gas fields to other existing gas fields with partial or complete elimination of the existing gas treatment and compression equipment at the first gas fields. Mathematical modeling of the development of a gas field is carried out with the determination of the required levels of extracted gas, the term and period of shutdown for each pad, group of gas wells. Based on the results of modeling the development of a gas field, certain levels of withdrawn gas, the period and periods of shutdown for clusters, groups of gas wells are established with the maintenance of the required level of gas withdrawal using modular compressor units and gas supply from some existing gas fields to other existing gas fields.

EFFECT: increasing the life and stability of operation of gas wells, gas collection systems, gas compression and treatment equipment with an increase in the gas recovery factor of the field.
