Herbicidal composition with increased herbicidal efficacy

An herbicide composition available as a concentrate for dilution with water or a ready-to-use oil-in-water emulsion which has a significantly reduced amount of active ingredient of a broadleaf herbicide. The composition combines the reduced amount of herbicide in a mixture of oil and emulsifier.. ... Suncor Energy Inc

Production of hydrocarbon using direct-contact steam generation

A process for in situ thermal recovery of hydrocarbons from a reservoir is provided. The process includes: providing an oxygen-enriched mixture, fuel, feedwater and an additive including at least one of ammonia, urea and a volatile amine to a direct-contact steam generator (dcsg); operating the dcsg, including contacting the feedwater and the additive with hot combustion gas to obtain a steam-based mixture including steam, co2 and the additive; injecting the steam-based mixture or a stream derived from the steam-based mixture into the reservoir to mobilize the hydrocarbons therein; and producing a produced fluid including the hydrocarbons.. ... Suncor Energy Inc

Process for flocculating and dewatering oil sand mature fine tailings

A process for dewatering oil sand fine tailings is provided and comprises a dispersion and floc build-up stage comprising in-line addition of a flocculent solution comprising an effective amount of flocculation reagent into a flow of the oil sand fine tailings; a gel stage wherein flocculated oil sand fine tailings is transported in-line and subjected to shear conditioning; a floc breakdown and water release stage wherein the flocculated oil sand fine tailings releases water and decreases in yield shear stress, while avoiding an oversheared zone; depositing the flocculated oil sand fine tailings onto a deposition area to form a deposit and to enable the release water to flow away from the deposit, preferably done in a pipeline reactor and managing shear according to yield stress and cst information and achieves enhanced dewatering.. . ... Suncor Energy Inc

Production of hydrocarbon product and selective rejection of low quality hydrocarbons from bitumen material

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.. ... Suncor Energy Inc

Dispersion and conditioning techniques for thick fine tailings dewatering operations

Techniques are described that relate to enhancing flocculation and dewatering of thick fine tailings, for example by reducing process oscillations. One example method includes dispersing a flocculant into thick fine tailings having a turbulent flow regime to produce turbulent flocculating tailings; subjecting the turbulent flocculating tailings to shear to build up flocs and increase yield stress, to produce a flocculated material having a non-turbulent flow regime; and shear conditioning the flocculated material to decrease the yield stress and produce conditioned flocculated tailings within a water release zone; and dewatering the conditioned flocculated tailings, for example by employing sub-aerial deposition. ... Suncor Energy Inc

Spray oil and method of use therof for controlling turfgrass pests

A paraffinic spray oil and a method of using the spray oil for controlling turfgrass pests is disclosed. The spray oil comprises paraffinic oil and a quick break emulsifier, which is formulated as an oil-in-water (o/w) emulsion for use. ... Suncor Energy Inc

Processing of aqueous waste streams to remove naphthenic acids

A method is provided for the treatment of waste streams resulting from the processing of hydrocarbons that contain naphthenic acids, for example desalter brine resulting from the extraction or production of hydrocarbons from an oil sands reservoir. Naphthenic acids can be removed from these streams by removing oil-wet solids from the waste stream prior to conventional waste water processing, and the oil-wet solids can further be independently remediated to reduce naphthenic acid concentration for disposal.. ... Suncor Energy Inc

Improved turfgrass fungicide formulation with pigment

Oil-in-water fungicidal formulations are prepared having pigment dispersed therein, the pigment being stable within the oil-in-water emulsion as a result of the addition of suitable silicone surfactants and suitable emulsifiers. The formulations can be prepared either as a 2-pack formulation or as a single formulation. ... Suncor Energy Inc

Systems and methods for controlling production of hydrocarbons

There is provided systems and methods for controlling the inflow of materials into a production well during recovery of hydrocarbons from a hydrocarbon-containing reservoir. The system includes a flow control device configured to limit steam flow and hot water flow from the hydrocarbon-containing reservoir.. ... Suncor Energy Inc
