Abstract
The invention relates to methods and apparatus for creating multiple fractures in subterranean formations. The apparatus is a jetting tool having a plurality of sets of jetting nozzles so that the sets of nozzles are substantially parallel to one another such that parallel cavities may be formed substantially simultaneously in the formation. The jetting nozzles may be adapted to provide a fluid jet that flares outwardly from the nozzle. The nozzles also may be aligned such that cavities in the formation overlap to form a single cavity. The nozzles may be further adapted so that holes jetted into the casing thereby are still spaced from one another. Methods of fracturing subterranean formations using the apparatus are also disclosed.
