摘要: Degradable material assisted diversion (DMAD) methods for well treatment, DMAD treatment fluids, and removable plugs in downhole operations. A slurry of solid degradable is injected into the well, a plug formed, operation performed around diverter, then degraded removal. Degradation triggers can be temperature or chemical reactants, with optional accelerators retarders to provide desired timing In multilayer formation fracturing, isolates completed fracture while additional layers are sequentially fractured plugged, removed flowback from layers. an aqueous have solids phase including fluid viscoelastic surfactant. The mixture fibers particulate material.
