Abstract
A process for producing a solid foaming agent, and a process for using the foaming agent for the removal of water from flooded gas wells is provided. The foaming agent is formed by first combining a water soluable, nonionic polyethoxylated surfactant with urea to form a solid urea adduct, and compressing the urea adduct under high pressures into a shape of size and density to enable it to drop to the bottom of a column of water existing in the well. The urea adduct is dropped into the flooded well bore and gas produced through the water generates foam which is expelled from the well with the gas flow.
