Abstract:
A plurality of solid polymer particles including an aromatic epoxy crosslinked with a hardener having at least two amino groups and at least one of an aromatic ring or a cycloaliphatic ring is disclosed. The solid polymer particles are useful, for example, as proppants. Mixtures of the plurality of particles and other particles, fluids containing the plurality of particles, methods of making the plurality of particles, and methods of fracturing a subterranean geological formation are also disclosed.
Abstract:
A method of facilitating the removal of bitumen-containing mud from a substrate includes coating the substrate with a composition comprising nanoparticles and water, such that the bitumen-containing mud that adheres to the coated substrate may be more easily removed from the substrate than from an uncoated substrate. In one embodiment, the composition assists an aqueous terpene-based detergent to more effectively clean bitumen-containing mud from the painted steel undercarriages of trucks used in oil sands operations.
