1. A method for automatically determining hydraulic fracturing parameters, comprising:
obtaining hydraulic fracturing treatment (HF) data, wherein the HF data includes one or more of surface treatment pressure (STP), slurry rate, surface proppant concentration (SPC), or bottom hole proppant concentration (BHPC);
determining a Rate Shut-In (RSI) time from the HF data;
determining a Well Shut-In (WSI) time using the RSI time;
calculating an Instantaneous Shut-In Pressure (ISIP) based upon both the RSI and the WSI times, wherein determining the RSI time, the WSI time and calculating the ISIP value are automatically performed by one or more processors, and
modifying at least one of the STP, slurry rate, SPC, or BHPC using one or more of the RSI time, the WSI time, or the ISIP; and
executing a hydraulic fracturing treatment using the at least one modified STP, slurry rate, SPC, or BHPC.
