Challenge
Traditionally decisions regarding the optimum number and setting depths of valves in gas lifted wells have been made considering only a small number of operating scenarios. As a result, wells often do not perform as expected.
A lack of rigor also often exists when checking the suitability of proposed valve set up specifications over the expected life of well operating conditions. This often means that injection of all available lift gas at the deepest possible location cannot be achieved.
Solution
A more rigorous well life-cycle design process is available, incorporating both Petroleum Experts ‘Prosper’and proprietary Petroleum Technology Company software.
