With coiled tubing as a conduit for proppant-laden fracturing fluids, single or multiple zones can be stimulated consecutively during a single mobilization. New tools selectively isolate target pay zones without conventional rigs or wireline intervention to set mechanical plugs. Individual zones are treated separately to achieve optimal fracture length and conductivity. Case studies demonstrate the expanding scope and economic benefits of this technique.
