Dual String gas lift applications offer significantly reduced cost and environmental impact by utilizing a single well to independently produce two zones.
These have historically utilized a combination of Production Pressure Operated (PPO) valves in one string and Injection Pressure Operated (IPO) valves in the other to theoretically provide some level of control in each well, but the gas always ends up going to the weaker string. In Practice these systems are rife with multi-pointing, instability, and chatter leading many operators to only produce one string at a time or abandon dual string completions altogether.
Silverwell’s DIAL System solves the problems of IPO / PPO Dual String Completions by giving operators the ability to instantly and independently control gas lift in each string without intervention. Rather than the strings fighting each other for lift gas, the operator can control and optimize total production leading to more production, less cost, and reduced carbon impact.
