In a method for diverter fracturing, a water-based fracturing fluid including non-convex particles is introduced into a hydraulic fracture of a wellbore at a first location. Each non-convex particle is formed to interlock with another non-convex particle. A diverter plug is formed in the hydraulic fracture when multiple non-convex particles interlock. Flow of another water-based fracturing fluid is diverted to a second location due to the diverter plug, forming another hydraulic fracture at the second location.

Materials and method for diverter fracturing

Provided is a composition that may include an aqueous phase, and extremophilic bacteria having signal transduction chemotaxis machinery and nanoemulsion oil droplets including metal-silica nanoparticles attached to a surface thereof. Further provided is a method for treating an oil reservoir, that may include introducing into the oil reservoir an extremophilic bacteria having signal transduction chemotaxis machinery and nanoemulsion oil droplets including metal-silica nanoparticles attached to a surface thereof. Further provided is method for bacteria mediated enhanced oil recovery that may include introducing extremophilic bacteria downhole to an oil reservoir. The method may further include triggering cell lysis of the extremophilic bacteria, mobilizing the oil trapped by the biosurfactants released from lysed extremophilic bacteria, and producing the oil trapped by the biosurfactants from the oil reservoir.
