1. A computer-implemented method to regulate downhole fluid flow through a plurality of valves, comprising:
determining fluid flow through a plurality of valves;
in response to a determination that fluid flow through a valve of the plurality of valves is below a threshold due to particle buildup:
maintaining fluid flow through the valve while restricting production fluid flow through other valves of the plurality of valves to fluidly isolate a section of a well that is fluidly connected to the valve from other sections of the well that are fluidly connected to the other valves, wherein the other valves are valves of the plurality of valves having production fluid flows at or above the threshold;
injecting a treatment substance through the valve into the section of well;
after injecting the treatment substance, re-opening the other valves for production flow while restricting fluid flow through the valve for a threshold period of time;
after restricting fluid flow through the valve for the threshold period of time, determining fluid flow through the valve; and
re-opening the valve after a determination that the fluid flow through the valve is at or above a second threshold.
