ABSTRACT:
Dewatering of coal seams for facilitating the production of gas therefrom through a well is effected by treating the coal seam utilizing a well treatment fluid containing a dewatering aid which both enhances the permeability of the formation to water production and binds tenaciously to the coal surface so that the permeability enhancement benefits are realized over a long production term. The preferred dewatering surfactants used in the treatment fluid and the process of treating the well are selected from a group consisting of:
