A Steam-Assisted Gravity Drainage (SAGD) method for recovering hydrocarbons from a reservoir can include generating steam and COfrom feedwater, fuel and oxygen; transferring a steam-COmixture comprising at least a portion of the steam and at least a portion of the CO, to a proximate SAGD injection well; injecting the steam-COmixture 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.

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.

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

This invention consists of a method to enable methane recovery from hydrate reservoirs. The invention, in particular, relates to a Saltwater Hydrate Extraction Process (SHEP) in which high salinity water is injected into a hydrate reservoir into a lower horizontal well to promote and control gas production by hydrate decomposition to an upper deviated production well.

In situ process to recover methane gas from hydrates

A method for recovering natural gas from a group of subterranean zones containing natural gas, including injecting an amount of a displacing gas into a first subterranean zone, producing a first produced gas from the first subterranean zone, collecting an amount of the first produced gas wherein the quality of the collected first produced gas is higher than or equal to a threshold production quality for the first produced gas, injecting an amount of the first produced gas into a second subterranean zone wherein the quality of the injected first produced gas is higher than or equal to a threshold injection quality for the first produced gas, producing a second produced gas from the second subterranean zone, and collecting an amount of the second produced gas wherein the quality of the collected second produced gas is higher than or equal to a threshold production quality for the second produced gas.

Method for recovery of natural gas from a group of subterranean zones

A process for enhanced oil and gas recovery. An enriched flue gas is synthesized from utility plant flue gas. The enriched flue gas is customizable for specific requirements; however, the gas is formed to have a high concentration of carbon dioxide. This is used as an injectant for enhancing the liberation of gas and/or oil from subterranean formations. The injection elevates recovery while sequestering carbon dioxide from the power plant source.

Carbon dioxide enriched flue gas injection for hydrocarbon recovery

A variety of methods for thermal recovery of natural gas and bitumen from a formation containing the latter. In general, the methods incorporate a series of existing, but previously uncombined technologies. A modified flue gas from the steam generators conventionally used in a SAGD recovery operation is injected into the formation to enhance recovery with the produced fluids, natural gas, bitumen, inter alia are further processed. The injection of the flue gas conveniently is disposed of and further acts to repressurize the formation which otherwise becomes depressurized when depleted of natural gas. Accordingly, environmental and economic advantages are realized with the methodology.
