Abstract
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.
