METHOD FOR OPERATION OF GAS WELLS AT COMPLETION STAGE OF RESERVOIR ENGINEERING Russian patent published in 2010 - IPC E21B43/00 

Abstract RU 2405916 C2

FIELD: oil and gas production.

SUBSTANCE: method includes installation of device for intensification of gas bleeding by means of pressure reduction in zone of gas bleeding and additional gas inflow from bed into gas wells with direction of products into system of gas collection at wellhead in bore of gas wells. According to invention, debit of gas wells is increased up to value providing for speed of gas flow in lifting string, required for continuous carry-over of liquid-condensate from gas wells bottomhole, which prevents coverage of perforation holes with liquid condensate in gas wells bore.

EFFECT: increasing or maintenance of wells debit, and also durable stable operation of wells without interference of service personnel.
