    摘要: The present invention is directed to a method and apparatus for fracturing a subterranean formation which use a liner fracturing tool. The liner fracturing tool consists of a liner, with at least one jet extending through the liner. During fracturing operations, fracturing fluid is pressured through the jet to form microfractures. Fractures are formed by the stagnation pressure of the fracturing fluid. The jets may be mounted within a jet holder that may be dissolved following fracturing operations to allow reservoir hydrocarbons to flow into the liner more readily.

    摘要: 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.

    摘要: A method and apparatus for use in hydrocarbon exploration. The method and apparatus improve downhole flow back control in oil and/or gas wells by controlling fluid entry into the well bore. Either a single limited entry opening or a small cluster of limited entry openings is provided in a well liner or casing and cement sheath allowing fluid communication between a region of a well bore and a subterranean reservoir. The method also uses the limited entry opening or the cluster during an injection treatment of the subterranean reservoir to control fluid entry. The method also provides a proppant flow back treatment following the injection treatment of the subterranean reservoir.
