Abstract
Techniques for reducing a carbon emissions intensity of a fuel includes injecting a carbon dioxide fluid into a first wellbore; producing a hydrocarbon fluid from a second wellbore to a terranean surface; and producing a fuel from the produced hydrocarbon fluid, the fuel including a low-carbon fuel and assigned an emissions credit based on a source of the carbon dioxide fluid.
Claims15
A method for reducing a life cycle carbon emissions intensity of a fuel, comprising:
- injecting a carbon dioxide fluid from a source of atmospheric carbon dioxide fluid into a first wellbore;
- producing a hydrocarbon fluid from a second wellbore to a terranean surface;
- producing a fuel from the produced hydrocarbon fluid;
- determining a life cycle emissions credit for the produced fuel based on the injection of the atmospheric carbon dioxide fluid;
- and
- determining a reduced life cycle carbon emissions intensity value of the produced fuel based on the determined life cycle emissions credit.
A method for reducing a life cycle carbon emissions intensity of a fuel, comprising:
- capturing a carbon dioxide fluid from a source that comprises an industrial process that captures carbon dioxide from the atmosphere, the industrial process comprising:
- directing ambient air through a packing material;
- flowing a carbon dioxide absorbing fluid over the packing material;
- capturing the carbon dioxide from the ambient air in the carbon dioxide absorbing fluid;
- and
- separating the captured atmospheric carbon dioxide from the carbon dioxide absorbing fluid;
- providing the captured carbon dioxide fluid to a refining process;
- producing a fuel from the refining process;
- determining a life cycle emissions credit for the produced fuel based on the injection of the atmospheric carbon dioxide fluid;
- and
- determining a reduced life cycle carbon emissions intensity value of the produced fuel based on the determined life cycle emissions credit.
A method for reducing a life cycle carbon emissions intensity of a fuel, comprising:
- receiving a fuel refined from a raw hydrocarbon fluid produced from a geologic formation into which a fluid that contains carbon dioxide captured from the atmosphere was injected;
- determining a lifecycle emissions credit for the refined fuel based on the injection of the atmospheric carbon dioxide fluid;
- determining that the fuel comprises a reduced life cycle carbon emissions intensity value based on the determined life cycle emissions credit;
- and
- providing the fuel as a low-carbon fuel based on the reduced life cycle carbon emissions intensity value.
A method of producing a hydrocarbon fuel with reduced life cycle carbon intensity, the method comprising:
- receiving a hydrocarbon fluid that has been produced from a geologic formation through a wellbore to a terranean surface, the hydrocarbon fluid produced, at least partially, from the geologic formation with an atmospheric carbon dioxide fluid injected into the geologic formation;
- refining the received hydrocarbon fluid into a fuel;
- determining a life cycle emissions credit for the refined fuel based on the injection of the atmospheric carbon dioxide fluid;
- and
- determining a reduced life cycle carbon emissions intensity value of the produced fuel based on the determined life cycle emissions credit.
