Claim:
1. A fracturing-fluid additive composition comprising bio-oil, wherein said fracturing-fluid additive composition contains from 56 wt % to 90 wt % water and from 10 wt % to 25 wt % carboxylic acids, and wherein said bio-oil is produced by a process of: (a) introducing biomass to a reactor operated under pyrolysis conditions to convert said biomass to a reaction mixture comprising condensable vapors, non-condensable gases, and solid biochar; (b) removing at least some of said biochar from said reaction mixture, to produce an intermediate mixture comprising said condensable vapors and said non-condensable gases; (c) introducing said intermediate mixture to at least one heat exchanger operated under effective conditions to condense said condensable vapors, thereby generating said bio-oil from said condensable vapors; and (d) collecting said bio-oil.
