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.
Claims20
A treatment fluid, comprising:
- a plurality of particles comprising an Apollonianistic particle size distribution comprising particles of a Pickering emulsion comprising a first liquid phase dispersed in a continuous second liquid phase and a plurality of colloidal particles adsorbed to a liquid-liquid interface between the first liquid phase and the second liquid phase.
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.
