Abstract:
Design and preparation of a smart system, including a hydrophilic polymer nanoparticle as a core material and a hydrophilic-hydrophobic block copolymer as a coating nanolayer for use in a smart core-shell nanostructure flooding during enhanced oil recovery (EOR) process. The hydrophilic polymers are prepared by an inverse emulsion method. The central core of this nanostructure includes hydrophilic polymer. The nanolayer can be a surfmer. The binary properties of the shell and hydrophilic polymers increase the water viscosity in the water-oil interface and enhance oil recovery.
Abstract:
A method for fabrication of ordinary porous media and fractured porous media with controllable characteristics is disclosed. The method comprises the steps of: providing a cylindrical container and sealing one end of the cylindrical container. The method further comprises fastening the sealed end of the cylindrical container with a lacy sheet for connecting to a vacuum pump and packing the cylindrical container with glass beads to achieve predetermined porosity and permeability using vacuum. Finally placing the packed container in a furnace until reaching a retention time at a predefined rate of temperature enhancement, and separating a fabricated core from the packed container.
