Developing a Novel Temperature Model in Gas Lifted Wells to Enhance the Gas Lift Design
In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. Also g...
متن کاملMature Assets: Low-cost plant upgrades marginal gas fields
Large volumes of low-BTU gas from big fields can be processed in large volumes in centralized processing plants using conventional technology. However, significant volumes of N2-induced low-BTU gas reside in marginal fields owned by small operators with limited financial and technical resources. Such production is often characterized by low feed volumes and pressures, remote locations, and rapi...
متن کاملInfluence of Altitudes and Air Humidity to the Minimum Gas Injection Rate in Air Underbalanced Drilling
Three aspects, such as the optimization of calculation model for the minimum gas injection rate, the effect of elevation on the minimum gas injection rate, the effect of air humidity on the minimum gas injection rate, have been reviewed in this paper. Considering the influence of altitude and air humidity, correction factor for gas injection rate is calculated. The value of gas injection for al...
متن کاملStabilization of Gas Lifted Wells
Increased production from gas lifted oil wells can be achieved by use of feedback control. Without control the well system may have large oscillations in the flow rate or stabilize itself at a non-optimal production point. These non-optimal production conditions give lower production and/or poor oil/water downstream separation. The study extends the newly introduced approach for controlling gas...
