Embodiment Construction

[0029] figure 2 ：

[0030] In one embodiment of the invention, reference is now made to figure 2 , describes a method A for the production of oil and / or gas comprising the disposal of sulfur compounds. Method A includes step 1 in which sulfur and / or sulfur-containing compounds are obtained and optionally released into the formation. In step 2, at least a portion of the sulfur compounds are converted to a carbon disulfide formulation and / or a carbon oxysulfide formulation, optionally within the formation. In step 3, at the conclusion of the EOR operation, the oil and / or gas may be separated from the carbon disulfide formulation and / or carbon oxysulfide formulation, and the oil recovered from the subterranean formation, and the carbon disulfide formulation and / or carbon disulfide formulation may be separated within the formation. The carbon oxysulfide formulation is transformed into another compound.

[0031] step 1:

[0032] Obtaining the sulfur-containing compound ca...

Abstract

A system for producing oil and / or gas comprises a system for producing oil and / or gas comprising a formation comprising a mixture of oil and / or gas and a carbon disulfide formulation and / or a carbon oxysulfide formulation; a mechanism for releasing a separating agent into the formation, the separating agent adapted to separate the oil and / or gas from the carbon disulfide formulation and / or the carbon oxysulfide formulation.

Description

technical field [0001] The present invention relates to systems and methods for producing oil and / or gas. Background technique [0002] Sour natural gas contaminated with hydrogen sulfide-producing bacteria is currently produced in large quantities from natural gas wells, oil wells (eg as associated gas) and from natural gas reservoirs. The presence of hydrogen sulfide and other sulfur compounds in fuels and other gases has long been a concern for users and producers of such gases. In addition to the corrosion and other adverse effects of such impurities on equipment and processes, harmful emissions are generally generated from the combustion of natural gas due to the oxidation of sulfur compounds. The sulfur oxides produced can be a major cause of air pollution and can have detrimental effects on the environment. As increasingly stringent federal and state regulations are enacted in an effort to reduce or eliminate sulfur-containing emissions, there is consequent value in...
