1. A method of increasing hydrocarbon recovery from a wellbore penetrating a tight hydrocarbon formation, comprising:
injecting a fluid comprising an amide-based additive to reduce friction in the tight hydrocarbon formation;
inserting a hydro-jetting tool into the wellbore;
jetting a thermally controlled fluid against the wall of the wellbore, with reduced friction, to create a cavity in the wall, using the hydro-jetting tool;
subsequently injecting, through a coiled tubing and an annulus of the hydro-jetting tool, an amount of a proppant-laden slurry which is separate from the thermally controlled fluid into the wellbore such that the pressure in the wellbore increases and propagates one or more fractures extending from the cavity in the wall;
cooling the tight hydrocarbon formation using the proppant laden slurry by circulating the proppant-laden slurry within the cavity;
withdrawing the hydro-jetting tool from the wellbore; and
recovering the thermally controlled fluid, the proppant-laden slurry, and one or more hydrocarbons from the fracture in the formation;
wherein the thermally controlled fluid contains an erosive material comprising acid,
wherein the proppant-laden slurry is thermally controlled.
