"Processes to disintegrate the filter cake in a training subterru00e1nea, and to prevent the damage to the screen and other equipment subterru00e1aneo during placement in a training subterru00e1nea, screen or other equipment subterru00e1neo, and use of a polu00ecmero solid" a process for disintegrating The filter cake in an underground formation.This process comprises: (I) to incorporate in a fluid treatment of a solid polymer capable of being converted by hydrolysis into one or more organic acids; (II) introducing the treatment fluid in the subterranean formation; and (III) to allow the solid polymer hydrolysis in the presence of Water to produce organic acid such that the material soluble in acid inside the filter cake or training adThe present is dissolved.
