Abstract
A hydrocarbon well remediation/stimulation treatment based on an Y-Grade natural gas liquid injection fluid mixture, including prescribed amounts of gas, nanoparticles with wettability alteration properties, foaming agents (including nanoparticles with foam stabilization properties), and solvent additives. The fluid mixture may be tuned to address multiple factors contributing to production decline, such as liquid blockage, wettability properties, fines/debris/scale build-up and organic deposits, reservoir heterogeneity/permeability, and/or reservoir fluid and hydrocarbon compositions, resulting in hydrocarbon production enhancement. The treatment is typically applied with a Huff-n-Puff process, however may also be applied with a flooding process.
