Abstract

Methods and systems for carbon sequestration in conjunction with oil and gas operations. Carbon dioxide in the form of nanobubbles is used to supersaturate treated produced water. The supersaturated produced water is then injected into Class II injection wells for effective storage in underground formations in conjunction with enhanced recovery operations or the storage and disposal of produced water from production operations.

Claims (16)

1 . A method of carbon sequestration in conjunction with oil and gas operations, comprising the steps of:

supersaturating a previously-treated produced fluid stream with carbon dioxide nanobubbles; and

injecting the supersaturated produced fluid stream into a well.

2 . The method of claim 1 , further comprising the step of, after the step of injecting, introducing at least a portion of the supersaturated produced fluid stream into one or more subsurface formations.

3 . The method of claim 2 , further comprising the step of sequestering carbon in the one or more subsurface formations into which the supersaturated produced fluid stream has been introduced.

4 . The method of claim 1 , wherein the well is a Class II injection well.

5 . The method of claim 4 , wherein the Class II injection well is a disposal well.

6 . The method of claim 4 , wherein the Class II injection well is a hydraulic fracturing well.

7 . The method of claim 4 , wherein the Class II injection well is an enhanced recovery well.

8 . The method of claim 4 , wherein the Class II injection well is a waterflood well.

9 . The method of claim 1 , further comprising the step of generating carbon dioxide nanobubbles.

10 . The method of claim 9 , wherein the carbon dioxide nanobubbles are generated, in whole or in part, in a moveable trailer.

11 . The method of claim 1 , further comprising the step of:

prior to the step of supersaturating, injecting ozone or an ozone-oxygen mixture into the produced fluid stream.

12 . The method of claim 1 , further comprising the step of:

prior to the step of supersaturating, injecting nitrogen or a nitrogen-rich gas into the produced fluid stream.
