    Agua del Cajón Field produces from conventional and unconventional formations since 1970. Gas lift has achieved good results for several years in the field. But despite working properly in the tubing, it didn’t solve liquid accumulation in the perforated interval.

    Capex developed a customized bottom-hole equipment that optimizes well performance, by injecting gas lift below the packer. A cross-over packer with a concentric pipe design is used, allowing injected gas to be conducted through the annular space between them and to extract liquid and gas from the bottom of the well by the central tube of reduced diameter. The production gas can be produced with the liquid at the end of the pipe or rise through the annular space and join the liquid production and injected gas through a crossover located below the packer. The advantage of this system is that it ensures the removal of liquids from the lower part of the well with an optimized flow of injection gas.

    In the last 5 years, 25 devices were installed with operative success in all cases. Gas flow rate increased an average of 80% after the intervention. Liquid production increment is also observed in most cases. Reserves were gained as it was able to reduce the abandonment gas flow rate.
