The productivity of natural-gas and gas-storage wells is impaired by the accumulation of liquids in the well bore or in the productive formation around the well bore. Chemical stimulation methods of gas production offer many advantages. Such stimulative methods commonly uses energy available in the reservoir to perform operations that previously were done mechanically with external energy. Therefore, chemical methods often require less personnel and equipment than corresponding mechanical methods. Uses of foaming agents for removing liquids from gas well bores and to relieve capillary waterblocks from the productive formation around the well bore have been recently developed. Surfactants or surface-active agents were tested in the laboratory and in the field. However, only representative results of field testing in natural gas and gas-storage wells are presented in this report. Liquids in well bores were successfully removed by foaming them with surfactants. Liquids in the reservoir adjacent to the well bore were effectively removed with an alcohol-surfactant treatment. Reduction in reservoir liquid saturation was determined with the neutron well-logging technique. (22 refs.)
