Alfred R Jennings Jr: Simultaneous hydraulic fracturing using fluids with different densities. Mobil Oil Corporation, Alexander J McKillop, George W Hager Jr, Charles A Malone, November 15, 1994: US05363919 (67 worldwide citation)

Two spaced apart zones of a formation are simultaneously hydraulically fractured. A lower density fracturing fluid is injected into an upper zone of the formation via an annulus of a perforated wellbore communicating with the upper zone thereby causing a fracture to propagate. Simultaneously therewi ...
