Methods of producing transportation fuel
First Claim
1. A method of producing transportation fuel, comprising:
- providing a highly paraffinic formation fluid produced from a subsurface in situ heat treatment process to a gas/liquid separator, wherein a majority of the highly paraffinic formation fluid comprises highly paraffinic hydrocarbons having a boiling point distribution between −
5°
C. and about 350°
C.;
in the gas/liquid separator, separating from the highly paraffinic formation fluid a highly paraffinic hydrocarbon stream, wherein the separated highly paraffinic hydrocarbon stream has a boiling range distribution between about 50°
C. and about 350°
C., a total paraffinic content of at least 70% by weight, and a sulfur content of at least 0.01% by weight;
hydrotreating the separated highly paraffinic hydrocarbon stream to produce a hydrotreated highly paraffinic, low sulfur, hydrocarbon stream having a boiling range distribution between about 50°
C. and about 350°
C., a total paraffinic content of at least 70% by weight, a sulfur content less than the sulfur content of the separated highly paraffinic hydrocarbon stream, and a wear scar diameter of no greater than 0.9 mm;
distilling the highly paraffinic, low sulfur, hydrocarbon stream to produce a distilled highly paraffinic, low sulfur, hydrocarbon stream having a boiling range distribution between 150°
C. and 350°
C., a total paraffinic content of at least 70% by weight and a wear scar diameter of no greater than 0.9 mm; and
providing one or more additives to the distilled highly paraffinic, low sulfur, hydrocarbon stream having a boiling range distribution between 150°
C. and 350°
C., a total paraffinic content of at least 70% by weight, and a wear scar diameter of no greater than 0.9 mm to produce transportation fuel,wherein boiling range distribution is determined using ASTM Method D5307, total paraffinic content is determined using ASTM Method D6730, sulfur content is determined using ASTM Method D4294, and wear scar diameter is determined using ASTM Method D5001.

Abstract
Systems, methods, and heaters for treating a subsurface formation are described herein. At least one method for producing transportation fuel is described herein. The method for producing transportation fuel may include providing formation fluid having a boiling range distribution between −5° C. and 350° C. from a subsurface in situ heat treatment process to a subsurface treatment facility. A liquid stream may be separated from the formation fluid. The separated liquid stream may be hydrotreated and then distilled to produce a distilled stream having a boiling range distribution between 150° C. and 350° C. The distilled liquid stream may be combined with one or more additives to produce transportation fuel.
