Claims33
A method of absorbing gases into a liquid comprising:
- providing a stream of at least one desirable gas and at least one undesirable gas;
- exposing the gas stream to a liquid, so that the liquid absorbs more of the desirable gas than the undesirable gas;
- and
- releasing the liquid and gas mixture into an underground formation.
1 more element
A system for producing oil and/or gas comprising:
- a first formulation comprising a liquid;
- a second formulation comprising at least one desirable gas and at least one undesirable gas;
- a mechanism for absorbing at least a portion of the second formulation into the first formulation, to create a third formulation comprising the liquid, a larger portion of the desirable gas, and a smaller portion of the undesirable gas;
- and
- a mechanism for releasing at least a portion of the third formulation into an underground formation.
2 more elements
A method for producing oil and/or gas comprising:
- contacting a first formulation comprising carbon disulfide with a second formulation comprising at least one of hydrogen sulfide and carbon dioxide to create a third formulation comprising carbon disulfide and at least one of hydrogen sulfide and carbon dioxide;
- and
- releasing the third formulation into a formation.
