Tunable injection fluid based on natural gas liquids, gas, and nanoparticles for improved hydrocarbon recovery

A method for improved hydrocarbon recovery, comprising:

• injecting an injection fluid through an injection well into a hydrocarbon reservoir, wherein the injection fluid comprises Y-Grade natural gas liquids (NGL) and surface functionalized nanoparticles, wherein the Y-Grade NGL is an unfractionated hydrocarbon mixture that is a byproduct of a de-methanized hydrocarbon stream and comprises ethane, propane, butane, isobutene, pentane, and less than 1 percent methane, wherein the surface functionalized nanoparticles are configured to alter wettability of solid surfaces and alter the interfacial tension between fluids in the reservoir, wherein the injection fluid further comprises a foaming agent configured to generate foam in-situ within the reservoir for mobility control resulting in an efficient distribution within the reservoir, and wherein the foaming agent is a hydrophobic nanoparticle with a fluoro-based or siloxane-based surfactant surface immobilization;
• injecting a gas through the injection well into the reservoir to displace the injection fluid into the reservoir;
• and
• producing hydrocarbons from the resource reservoir via the injection well or a production well offset from the injection well.
