1. A method, comprising:
determining, by a computer processor and using a plurality of downhole sensors, time-derivative pressure data based on pressure data regarding a pump system that is performing a hydraulic stimulation operation using a hydraulic fracturing fluid in a geological region,
wherein the plurality of downhole sensors comprises a first downhole sensor coupled to a casing within a wellbore and a second downhole sensor coupled to a frac plug within the wellbore, and
wherein the hydraulic fracturing fluid is sent into a horizontal well in the wellbore at a predetermined flow rate during the hydraulic stimulation operation;
determining, by the computer processor, a moving average value based on the time-derivative pressure data and a predetermined time window;
determining, by the computer processor, a flow rate adjustment for the pump system based on the moving average value, an update interval for adjusting flow rates, and one or more predetermined flow rate rules, wherein a size of the predetermined time window is different from the update interval; and
transmitting, automatically by the computer processor and based on the flow rate adjustment, a command to the pump system that changes the predetermined flow rate of the hydraulic fracturing fluid within the hydraulic stimulation operation.
