摘要：A method and apparatus is provided for created multiple fractures in asubterranean formation with a single, continuous treatment operation. A plurality ofburst disk assemblies are included, each having an independent burst pressure and
corresponding to a specific interval to be treated, whereby the assemblies are arrangedon a work or completion string such that the assembly with the lowest burst pressure ispositioned at the toe, or lowest position, and subsequent assemblies have increasingburst pressures toward the heel of the string. As fluid is pumped down the string,pressure builds up to exceed the burst pressure of the first disk, allowing treatment fluidto contact the formation. Once a first interval treated or fractured, it may be isolatedthereby allowing pressure to again build up in the string and burst subseqent disks.
