One of the effective technologies for removing liquid accumulated at the bottom of gas wells and restoring the free movement of gas is the introduction of solid surfaceactive substances (surfactants) in a spherical or cylindrical form (chemical candle) to the bottomhole, contributing to the aeration of the foam mud at the bottom of the well and its rise to daylight surface. Foam formation reduces hydrostatic pressure on the formation, enhancing well productivity. The paper addresses the results of studies on a new composition of a solid surfactant for removing liquid from the bottom of gas wells. Proceeding from the studies carried out, it can be concluded that the considered composition has a high surface activity, wetting and multifunctional protective ability. A method is proposed for delivering a solid surfactant (chemical candles) to the bottom of a directional well.
