Abstract: The invention provides formulations for facilitating the removal of oil from a surface using a chisel composition, wherein the chisel composition includes a polymer having one or more binding points with a high affinity for the surface, and one or more hydrophilic segments that form a hydrophilic coating on the surface, rendering the surface water-wet and thereby facilitating the removal of oil from the surface. The invention also provides for methods of use of such formulations.

Abstract: The present invention relates to formulations comprising an inversion facilitator additive and an active emulsion polymer, and methods for their use. The formulation can comprise a water-in-oil emulsion having the active emulsion polymer in an aqueous phase of the water-in-oil emulsion. The active emulsion polymer can be a friction-reducing polymer, a flocculant polymer, or any other polymer suitable for delivery within the aqueous phase of the water-in-oil emulsion.

Abstract: The invention relates to a class of novel surfactants that have utility in the recovery and/or extraction of oil.

Abstract: Disclosed herein are systems and methods for removing fine particulate matter from a fluid, comprising a separator that separates an inflow fluid stream into an overflow fluid path and an underflow fluid path, where the underflow fluid path is treated with a tethering material that attaches to the coarse particulate matter to form tether-bearing anchor particles and where the overflow fluid path is treated with an activating material so that the activating material interacts with the fine particulate matter to form activated particles. After these treatments, the underflow fluid path containing the tether-bearing anchor particles is commingled with the overflow fluid path containing the activated particles, so that a removable complex is produced that can be removed in a settling facility, thereby removing the fine particulate matter from the fluid.

Abstract: The disclosure pertains to systems and methods for removing hydrocarbon contaminants from a contaminated solid using an environmentally benign extractant and an oleophilic absorber, where the environmentally benign extractant and the oleophilic absorber are separate components.

Abstract: Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a tailing solution.

Abstract: The systems and methods described herein provide for extracting bitumen from oil sands at ambient or subambient temperature, for example at temperatures between 0 degrees Centigrade and about 20 degrees Centigrade. The process includes the steps of forming a slurry by mixing the oil sands with water, adding an extractant to the slurry, agitating the extractant with the slurry, and collecting bitumen that separates from the slurry.
