11. A method for applying a multi-component treatment, said method comprising:
selecting, via a data processing system comprising a treatment procedure database, a treatment procedure from the treatment procedure database, wherein the selected treatment procedure includes relative fluid concentrations and reaction periods;
requesting, via the data processing system, downhole parameters from one or more downhole sensors;
generating, via the data processing system, one or more fluid component transport and mixing schedules based, at least in part, on the downhole parameters and the reaction periods;
transporting a first fluid from a surface of a wellbore through a first conduit to a first outlet positioned in the wellbore;
transporting a second fluid from the surface of the wellbore through a second conduit to a second outlet positioned in the wellbore; and
combining the first and second fluids within a confluence region within the second conduit or in the wellbore after passing through a mixing applicator located downhole that includes at least a portion of a discharge flow path from the first outlet, wherein the mixing applicator includes a pressure-sensitive flow control component that blocks flow to the first outlet when a fluid pressure of the first conduit is below a threshold pressure;
determining that one or more of the downhole parameters have exceeded a threshold; and
adjusting the one or more fluid component transport and mixing schedules based on the one or more downhole parameters that have exceeded the threshold.
