METHOD OF FRACTURING WITH APHRON CONTAINING FLUIDS

Subterranean formations may be stimulated by introducing into the formation a fluid containing a viscosifying agent and aphrons. The viscosifying agent may be a linear gel, crosslinked gel or a viscoelastic surfactant. The aphrons in the fluid move faster than the liquid phase of the fluid and thus...

Summary:Subterranean formations may be stimulated by introducing into the formation a fluid containing a viscosifying agent and aphrons. The viscosifying agent may be a linear gel, crosslinked gel or a viscoelastic surfactant. The aphrons in the fluid move faster than the liquid phase of the fluid and thus move toward the front of the fluid as the fluid is being pumped into the formation. The bubble barrier and radial-flow pattern of the fluid rapidly reduce the shear rate and raise the fluid viscosity, severely curtailing fluid invasion into the formation especially in those formations where high leak-off potential exists.
