•Presenting a technology of combining foam injection and compression to lift liquid in water flooded gas.•The technology contains foaming/de-foaming agent injection system and compressed natural gas injection system.•The natural gas in the gathering network from previous production is supplied to the systems.•The technology is expected to be especially useful and cost effectively in fields where electrical power is not available.•An example was selected to illustrate the technology and it has been applied successfully.
This article present a novel technology of combining foam injection and compression to lift liquid in water flooded gas wells in order to bring them back to production. In this technology, the natural gas in the gathering pipeline could be supplied to the natural gas generators. And then the generators provide electrical power to the injection systems which are skid mounted designed. The technology is helpful and cost effective to bring water flooded gas wells, especially to those located at a remote areas where electrical power is not available, back to production. In this paper, a typical water flooded gas well was selected to illustrate this technology and the successfully application of the technology indicates that engineers could bring water flooded gas wells back to production by using this novel artificial lift technology.
