Abstract
Methods include the injection of a gelled, gelling or gellable composition into a horizontal section of a well at a location, where produced well gases or a combination of well gases and injected gases are sufficient to move the pill through the horizontal section into heal section, sweeping the horizontal section of accumulated liquids. Once in the heal section, the pill and the accumulated liquids are uplifted to the surface resulting in a cleaned well.
