Pickering emulsion treatment fluid

Abstract

A well treatment fluid comprising a Pickering particle emulsion comprising particles of a first liquid phase dispersed in a continuous second liquid phase, and comprising a plurality of colloidal particles adsorbed to a liquid-liquid interface between the first liquid phase and the second liquid phase. Methods, equipment and/or systems for treating a subterranean formation utilizing such treatment fluids are also disclosed.

         15 . A method, comprising:
 dispersing a first liquid phase in a second liquid phase in the presence of a plurality of colloidal particles under conditions sufficient to produce a Pickering emulsion comprising a plurality of Pickering emulsion particles comprising the first liquid phase dispersed in the continuous second liquid phase, and comprising at least a portion of the plurality of colloidal particles adsorbed to a liquid-liquid interface between the first liquid phase and the second liquid phase;   mixing the Pickering emulsion in a carrier fluid to produce a treatment fluid comprising a plurality of particles having an Apollonianistic particle size distribution comprising particles of the Pickering emulsion; and   circulating the treatment fluid into a wellbore.   
     
     
         16 . The method of  claim 15 , further comprising forming a pack of the solids in the wellbore, wherein the pack comprises proppant and at least one particle size distribution mode comprising the particles of the Pickering emulsion. 
     
     
         17 . The method of  claim 16 , wherein at least a portion of the plurality of colloidal particles is freely dispersed in the treatment fluid, and wherein the pack comprises at least one particle size distribution mode of the freely dispersed colloidal particles. 
     
     
         18 . The method of  claim 16 , further comprising removing at least a portion of the particles from the pack to form a permeable proppant pack. 
     
     
         19 . The method of  claim 18 , further comprising producing or injecting a fluid through the permeable proppant pack. 
     
     
         20 . The method of  claim 19 , wherein the permeable proppant pack is disposed in a fracture.
