Methods for producing hydrocarbon fluids with reduced water-oil ratio by utilizing oil-wet petroleum coke proppant particles during hydraulic fracturing

A method for making modified coke proppant particles, comprising:

• performing at least one wettability alteration treatment on petroleum coke proppant particles by:
• (i) reacting the petroleum coke proppant particles with an organosilane;
• and
• (ii) thermally post-treating the petroleum coke proppant particles at a temperature in a range from 400° C. to 1200° C. for a duration in a range from 8 hours to 24 hours to generate modified petroleum coke proppant particles.

A method for producing hydrocarbon fluids via a hydrocarbon well, comprising:

• providing petroleum coke proppant particles;
• performing at least one wettability alteration treatment on the petroleum coke proppant particles, the wettability alteration treatment comprising reacting the petroleum coke proppant particles with an organosilane and thermally post-treating the petroleum coke proppant particles at a temperature in a range from 400° C. to 1200° C. for a duration in a range from 8 hours to 24 hours to generate modified petroleum coke proppant particles;
• for each of a plurality of stages of a hydrocarbon well, introducing a fracturing fluid comprising a carrier fluid and the modified petroleum coke proppant particles into a subterranean formation via a wellbore of the hydrocarbon well;
• and
• producing hydrocarbon fluids from the subterranean formation via the wellbore of the hydrocarbon well.
