1. A method of reducing injection pressure associated with a hydrocarbon resource recovery operation, the method comprising:
introducing a treatment fluid comprising a biochelant and a solvent; and
contacting the treatment fluid with a surface of hydrocarbon resource recovery operation that comprises asphaltenes, paraffins, or both for a time period sufficient to reduce an injection pressure of the injection well by equal to or greater than about 25%.
