    Abstract: A Steam-Assisted Gravity Drainage (SAGD) method for recovering hydrocarbons from a reservoir can include generating steam and CO2 from feedwater, fuel and oxygen; transferring a steam-CO2 mixture comprising at least a portion of the steam and at least a portion of the CO2, to a proximate SAGD injection well; injecting the steam-CO2 mixture into the SAGD injection well; obtaining produced fluids from a SAGD production well underlying the SAGD injection well; transferring the produced fluids for separation proximate to the SAGD production well; separating the produced fluids into a produced gas and a produced emulsion; transferring the produced emulsion for separation proximate to the SAGD production well; separating the produced emulsion to obtain a produced hydrocarbon-containing component and produced water; supplying at least a portion of the produced water as at least part of the feedwater; and supplying the produced hydrocarbon-containing component to a central processing facility.

    Abstract: Provided herein are stabilized, ready-to-use, quick break emulsion compositions (oil-in-water emulsion compositions), and in particular, stabilized paraffinic spray oil compositions and methods of using these compositions for controlling plant pests such as harmful insects and fungi. The oil-in-water emulsion compositions comprise a stabilizer which is benzoic acid, benzoic acid salt, benzoic acid derivative, paraben or a mixture thereof.

    Abstract: Hydrocarbon recovery can involve operating flow control devices distributed along a horizontal well based on temperatures of hydrocarbon-containing fluids at a plurality of locations along the horizontal well. The temperatures of hydrocarbon-containing fluids can indicate a presence of a hotter overlying reservoir region and an adjacent colder overlying reservoir region. The operation of the distributed flow control devices can involve reducing flow of hydrocarbon-containing fluid from the hotter overlying reservoir region into the horizontal well, while providing fluid communication and pressure differential between the colder overlying reservoir region and the production well, sufficiently to cause hot fluids surrounding the colder overlying reservoir region to be drawn into and induce heating of the colder overlying reservoir region.
