PolyPhronICS™ is used under numerous field conditions to reduce or completely eliminate the need for conventional lost circulation materials. This feature is thought to result from several mechanisms. One is the significant increase in low-shear rate viscosity that occurs. The second mechanism is the expansion of the bubbles to a size that effectively air-lock fluids in a porous formation. A third mechanism is the potential, instantaneous lowering of fluid density on a micro-environmental basis as bubble expansion takes place during the loss to the formation.
