摘要： Compositions containing a first reactant; an emulsion comprising a surfactant and silicon dioxide (SiO2) nanoparticles; and a carrier fluid containing a second reactant and methods of making. When the first and second reactants react, they generate heat. At a first time, the emulsion surrounds the first reactant, and the carrier fluid with the second reactant surrounds the emulsion. At a second time, the emulsion surrounds a first portion of the first reactant; and a second portion of the first reactant surrounds the emulsion.

摘要： Example methods and systems are described for evaluating an effectiveness of ceramic particles to recover heavy oil from a subterranean region. In some aspects, a heavy oil recovery evaluation system includes a vessel containing a mixture of heavy oil and sand, the vessel including a chamber to receive a plurality of ceramic particles and water, a probe connected to the vessel to transfer energy from an energy source for energizing the plurality of ceramic particles, wherein the energized ceramic particles convert the water into steam to recover the heavy oil from the mixture, and a computer system connected to the vessel to evaluate an effectiveness of the plurality of ceramic particles to recover heavy oil from the mixture.
