By combining data acquisition and automation with proven gas lift engineering techniques, csGasLift provides the user with the ability to accurately design and maintain efficiency of gas lift production systems or naturally flowing wells. Additionally, root causes of failures can be systematically identified using troubleshooting and sensitivity analysis tools.
The user can perform stability-analysis of the system to predict casing/tubing heading. The dynamic unloading simulator captures the transient nature of the unloading process providing better design and analysis. Availability of various reservoir, multi-phase flow and temperature prediction models empowers the user to accurately predict pressure and heat losses.
The software's analytical features are used to assure stable production. Operation of the valves during unloading are illustrated graphically for easy analysis. The simulation uses a finite difference scheme that simultaneously solves the time-dependent mass and the momentum and energy balance equations.
The tool provides a means of choosing the best correlation for the wells. Gas lift unloading valve spacing and design can be done for injection pressure operated (IPO), production pressure operated (PPO), and proportional response (PR) valves. Based on data and modeling, the software takes into account the dynamics of each gas lift valve for more accurate flow prediction.
In addition to single well analysis, the software calculates the optimal flow from a cluster of gas lift wells. csGasLift allocates either a limited or unlimited amount of injection gas to the wells based on the system's performance with economic and physical constraints.
