METHOD OF PRODUCT RECOVERY FROM STOPPED FLOWING WELL Russian patent published in 2003 - IPC

FIELD: oil and gas producing industry; applicable in oil recovery from wells ceased flowing due to dropped formation pressure or increased water encroachment. SUBSTANCE: method includes supply of gas from surface to well with ceased flowing; lifting of gas-fluid mixture with various gas-fluid components ratio through lifting channel formed by space of tubing string in well or through annular space between tubing string and well walls. Mixture is supplied to product collector. Well with ceased flowing is connected with flowing well by means of pipeline. Oil-gas products completely or partially are supplied from flowing well to well with stopped flowing with subsequent lifting of these products through lifting channel together with products of said well. If only a part of oil-gas products from flowing well is supplied to said well, ratio of gas and oil components in it is left invariable or varied by separation in separator included in pipeline interconnecting wells. A part of oil or gas component is supplied to collector of product to bypass the well stopped flowing. EFFECT: provided product recovery under conditions of absence of high-pressure gas source, and stable operating conditions. 2 dwg
