Benefits of technology

[0009]In one aspect, the invention provides a system comprising a mechanism for recovering oil and / or gas from an underground formation, the oil and / or gas comprising one or more sulfur compounds; a mechanism for converting at least a portion of the sulfur compounds from the recovered oil and / or gas into a carbon oxysulfide formulation; and a mechanism for releasing at least a portion of the carbon oxysulfide formulation into the formation.

Problems solved by technology

In addition to the corrosive and other adverse effects that such impurities have upon equipment and processes, noxious emissions are commonly produced from combustion of the natural gas as a result of oxidation of the sulfur compounds.
The resulting sulfur oxides can be a major contributor to air pollution and may have a detrimental impact upon the environment.

Embodiment Construction

[0029]Referring now to FIG. 2, in one embodiment of the invention, process A for producing oil and / or gas, which includes disposing of a sulfur compound is illustrated. Process A includes step 1 where oil and / or gas is recovered from an underground formation, the oil and / or gas including a sulfur compound. In step 2, at least a portion of the sulfur compound from the oil and / or gas is converted into a carbon oxysulfide formulation. In step 3, at least a portion of the carbon oxysulfide formulation or a mixture comprising a carbon oxysulfide formulation may be released into a formation.

[0030]The recovery of oil and / or gas with a sulfur compound from an underground formation may be accomplished by any known method. Suitable methods include subsea production, surface production, primary, secondary, or tertiary production. The selection of the method used to recover the oil and / or gas from the underground formation is not critical.

[0031]In one embodiment, oil and / or gas with a sulfur co...

Abstract

A system including a mechanism for recovering oil and/or gas from an underground formation, the oil and/or gas comprising one or more sulfur compounds; a mechanism for converting at least a portion of the sulfur compounds from the recovered oil and/or gas into a carbon oxysulfide formulation; and a mechanism for releasing at least a portion of the carbon oxysulfide formulation into a formation.

Description

FIELD OF THE INVENTION[0001]The present disclosure relates to systems and methods for producing oil and / or gas.BACKGROUND OF THE INVENTION[0002]Substantial amounts of sour natural gas are currently being produced from natural gas wells, oil wells (for example, as associated gas), and from natural gas storage reservoirs that have been infected with hydrogen sulfide producing bacteria. The presence of hydrogen sulfide and other sulfur compounds in fuel and other gases has long been of concern for both the users and the producers of such gases. In addition to the corrosive and other adverse effects that such impurities have upon equipment and processes, noxious emissions are commonly produced from combustion of the natural gas as a result of oxidation of the sulfur compounds. The resulting sulfur oxides can be a major contributor to air pollution and may have a detrimental impact upon the environment. Increasingly stringent legislation and federal and state regulations have accordingly...
