Paper Number: SPE-442-PA
Published: 01 March 1963
...Glenn Beadle To study continuous- and intermittent-flow gas-lift wells, it is necessary to evaluate the facilities that the well fluids must pass through to reach the storage point. This paper deals with surface back-pressure and its effect on continuous-and intermittent-flow gas lift. Particular...

... was carried out using 2 3/8" tubing of 63 ft in length. The liquid being lifted was water and compressed air was used to lift the water. Introduction As reservoir pressure declines, wells producing by means of continuous flow gas lift need to be changed to intermittent flow gas lift in order to maintain...

... to intermittent gas lift. Unfortunately, it is not feasible to produce wells with tubing flow gas lift or intermittent gas lift with the typical downhole equipment configuration used in annulus flow wells. Therefore, transitioning to these late-life artificial lift configurations has required a workover rig...

... gathered in the wellbore. The advantage of intermittent flow gas lift over the continue gas lift is periodic need of high-pressure gas. On the other hand, since gas is injected intermittently over specific period of time, it is not capable of producing at high volume rate compared to continuous flow gas...

... ]. The oil then flows to the stock tank while the mixture of injected and produced gas flows to the compressor suction unit, then the gas is re-squeezed and completes the cycle [ 3 ]. Oil wells with low rates or reservoir pressures, it is desirable to gas-lifted the oil well intermittently. Due to its cyclic...

... in use since the late 1800's. Gas lift, in its two commonly used schemes, known as continuous and intermittent lift, is realized by the injection of high pressure gas in a well, in order to create the necessary flowing bottomhole pressure to produce the desired rate of crude. Continuous gas lift (Fig...
