Abstract
A method includes injecting an injection fluid through a well and to a depth of a formation, where the injection fluid includes phase-changing nanodroplets having a liquid core and a shell. The method also includes exposing the phase-changing nanodroplets to an external stimulus at the depth of the formation, wherein the liquid core of the phase-changing nanodroplets undergoes a liquid-to-vapor phase change causing the phase-changing nanodroplets to expand, and stimulating the formation at a near wellbore region by expansion of the phase-changing nanodroplets.
Claims6
A method comprising:
- providing an injection fluid comprising phase-changing nanodroplets and an aqueous-based fluid wherein the phase-changing nanodroplets comprise:
- a liquid core;
- and
- a shell;
- injecting the injection fluid through a well and to a depth of a formation;
- exposing the phase-changing nanodroplets to an external stimulus at the depth of the formation, wherein the liquid core of the phase-changing nanodroplets undergoes a liquid-to-vapor phase change causing the phase-changing nanodroplets to expand;
- and
- stimulating the formation at a near wellbore region by expansion of the phase-changing nanodroplets.
