  • Publication number: 20190309214
    Abstract: The present disclosure relates to a method and a system for improving recovery of fluids comprising natural gas and water from a reservoir via at least one oil/gas well connected to at least one flowline/pipeline network. For improving recovery of fluids, a composition containing a specific foaming composition is injected at a pre-determined location at the oil/gas well and/or the flowline/pipeline network. The foaming composition is delivered to the predetermined injection location via umbilical. The foaming composition is then naturally agitated with the water and converted to foam. The agitation is carried out by the natural gas. The foam formed reduces the interfacial surface tension between the natural gas and the water, and thereby facilitates reduction in liquid holdup in the flowline/pipeline network.
