There are numerous gas-condensate fields that are maturing with rising liquid levels around the wellbores which reduces gas production and escalates corrosion. Cost-effective approaches are needed to revive and prolong gas production. Foamers are among the most inexpensive methods to remove liquid loading. Combinational foamer and corrosion inhibitor products are used to prevent corrosion and enhance productivity. However, there are many difficulties in combining different production chemicals, especially to create a stable homogeneous product for high temperatures application. In this paper, research works to provide the combination corrosion inhibitor - foamer products that have high temperature stability above 350°F and high flash point above 45 °C are described. The corrosion inhibition efficiency in protecting mild steel under severe sour corrosion conditions up to 350°F and partial pressures of 100 psi CO2 and 100 psi H2S are presented. Foaming performance in different liquid compositions is discussed. In addition, the selection of candidate wills for treatment with a newly created software is introduced. The software uses liquid loading equations and incorporates the reduction of surface tension and liquid density by the combination product.
