Abstract
A method for producing multiple fractures by a single operation from a single wellbore which penetrates a fracture interval which, in turn, includes a plurality of zones which break-down under different fracturing pressures. Fracturing fluid is delivered from a workstring directly to different levels within a section of the wellbore which lies adjacent the fracture interval through a plurality of alternate paths which, in turn, lie substantially adjacent to the zones to be fractured.
