Title:
DUAL MECHANISM THICKENING AGENTS FOR HYDRAULIC FRACTURING FLUIDS
Document Type and Number:
WIPO Patent Application WO/2014/036498
Kind Code:
A3
Abstract:
The present invention relates to multi-arm star macromolecules which are used as thickening agents or rheology modifiers, including use in hydraulic fracturing fluid compositions. In one aspect of the invention, a star macromolecule is capable of thickening via a dual mechanism comprising (1) self-assembly of the hydrophobic polymerized segments of the star macromolecules via hydrophobic interactions or associations, and (2) association, reaction, or combination of the hydroxyl-containing polymerized segments of one or more of the star macromolecules.
