FIELD: gas production, particularly to produce gaseous hydrocarbon from underground reservoir. ^ SUBSTANCE: method involves drilling vertical producing well to ground surface; stimulating fluid including gaseous and liquid fractions inflow from underground reservoir into producing well within production interval; separating reservoir fluid into gaseous component and liquid one along with gaseous component flow rate control in vertical producing well to maintain gaseous component flow rate below threshold flow rate value, which provides reservoir fluid separation inside producing well without the use of separator; delivering gaseous component to ground surface via producing well; accumulating liquid component in producing well to create liquid column having pressure within producing well draining interval exceeding that of surrounding reservoir; providing liquid draining from liquid column in surrounding reservoir along with producing well wall treatment within draining interval and/or reservoir treatment around draining interval to increase liquid discharge into surrounding reservoir. ^ EFFECT: possibility to separate reservoir fluid into gaseous and liquid components without specially adapted separator usage. ^ 9 cl, 6 dwg, 6 tbl
