A method for removing hydrocarbons from a solid phase and recovery thereof comprising the steps of

washing the solid phase contaminated with hydrocarbons by means of a composition comprising at least a surfactant so as to obtain a clean solid surface and a hydrocarbon-rich aqueous solution,
separating the hydrocarbon-rich aqueous solution from the clean solid phase, and
treating the hydrocarbon-rich aqueous solution by means of electrocoagulation/electroflotation to recover the hydrocarbons.

A method for producing oil, comprising injecting water and a solvent into a formation; producing a mixture comprising water, solvent, oil, and gas from the formation; separating the mixture into a first stream comprising oil, water, and a first portion of the solvent, and a second stream comprising gas and a second portion of the solvent, and exposing the second stream to water to remove the second portion of the solvent from the gas.

Methods are described for the production of a hydrocarbon product and selective rejection of low quality hydrocarbons from a bitumen-containing material, where product quality, production yield, processing input requirements, and environmental benefits are assessed for selecting a candidate method for deployment. The methods facilitate selection and deployment of sustainable hydrocarbon production operations rather than focusing on maximizing volumetric yield of hydrocarbons.

The present invention relates to a method for flocculating and dewatering oil sands fine tailings. Said method comprises mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The material is then dynamically mixed in an in-line reactor to break down the dough-like material to form microflocs having an average size of 1 to 500 microns, and to release water. The internal diameter of the in-line reactor is at most five times the internal diameter of the inlet pipe of the reactor. The suspension of microflocs has a viscosity of at most 1000 cP and a yield stress of at most 300 Pa.

The present embodiments generally relate to methods for the treatment of tailings, e.g., oil sands tailings, including methods comprising the use of one or more flocculants, one or more coagulants and one or more oxidants to treat said tailings and/or to improve the performance of said one or more flocculants.

A process includes: (a) injecting a steam composition into a subterranean location containing bitumen, the steam composition containing an alkylene glycol ether and steam, wherein the alkylene glycol ether is other than a glycol ether amine; and (b) recovering bitumen from the subterranean location to above the ground.

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