Abstract
A well casing penetrating a plurality of subterranean hydro carbon-bearing formations is perforated adjacent select ones of such hydrocarbon-bearing formations that are expected to exhibit at least a minimum pressure increase during fracturing operations. A fracturing fluid is pumped down the well through the perforations, and into the formations so as to fracture each of the select formations during a single fracturing operation.
