1. A method of forming a plugging cement patty, comprising:
mixing a plurality of inorganic particles, an inorganic binder, an organic binder, and a liquid at a mixing temperature greater than a hydration point temperature of the organic binder to form a plugging mixture comprising a viscosity in a range from about 1 cP to about 100 cP;
dispensing the plugging mixture at a dispensing temperature greater than the hydration point temperature; and
cooling the plugging mixture to a cooled temperature less than the hydration point temperature to increase the viscosity of the plugging mixture and form the plugging cement patty.
