Beschreibung
Zusammenfassung:	The present invention relates to the stimulation of wells penetrating subterranean formations. A method of differ-ential etching of the subterranean fracture wherein nonuniform deposition of a masking material on the fracture surface or face is provided; subsequent treatment by an acid or a reactive fluid generates a heterogeneous etch pattern on the fracture surface, the etch pattern is largely influenced by the placement geometry of the masking material upon closure these irregularities provide mis-match of geometry that leave open conductive channel in the fracture.
