Abstract
A method of treating a formation fluid includes providing formation fluid from a subsurface in situ heat treatment process. The formation fluid is separated to produce a liquid stream and a first gas stream. The first gas stream includes carbon dioxide, hydrogen sulfide, hydrocarbons, hydrogen or mixtures thereof. Molecular oxygen is separated from air to form a molecular oxygen stream comprising molecular oxygen. The first gas stream is combined with the molecular oxygen stream to form a combined stream comprising molecular oxygen and the first gas stream. The combined stream is provided to one or more downhole burners.

A method of treating a formation fluid, comprising:
- providing formation fluid from a subsurface in situ heat treatment process;
- separating the formation fluid to produce a liquid stream and a first gas stream, wherein the first gas stream comprises carbon dioxide and hydrogen sulfide;
- separating molecular oxygen from air to form a molecular oxygen stream comprising molecular oxygen;
- combining the first gas stream with the molecular oxygen stream to form a combined stream comprising molecular oxygen and the first gas stream;
- and
- providing the combined stream to one or more downhole burners.
A method of treating a formation fluid, comprising:
- providing formation fluid from a subsurface in situ heat treatment process;
- separating the formation fluid to produce a liquid stream and a first gas stream, wherein the first gas stream is selected from a group consisting of carbon dioxide, hydrogen sulfide, hydrocarbons, hydrogen, and mixtures thereof;
- applying current to water to form a molecular oxygen stream;
- heating the water by applying energy from a nuclear power source;
- combining the first gas stream with the molecular oxygen stream to form a combined stream comprising molecular oxygen and the first gas stream;
- and
- providing the combined stream to one or more downhole burners.
