Claim 14:
15. A method for detecting the occurrence of an event at a well comprising:
recording a first set of measurements collected from the well with a flow rate sensor disposed on a downhole tool; wherein the measurements are collected from a treatment fluid flowing in the well;
transmitting the recorded measurements to an information handling system for processing; wherein the information handling system is disposed on a surface of the earth; wherein the downhole tool comprises a receiver and a transmitter configured to communicate with the information handling system;
processing the recorded measurements to provide a first set of data;
calculating a first score based on the first set of processed data;
comparing the first score to a predetermined rule based on a specified time frame; and
altering a flow rate of the treatment fluid with a valve by adjusting a flow path through the valve based on the score comparison by an operator;
recording a second set of measurements collected from the well;
processing the second set of recorded measurements to provide a second set of data;
calculating a second score based on the second set of processed data;
wherein the first set of processed data and the second set of processed data is the number median of absolute difference from normal;
combining the first score and the second score using a weighted average; and
comparing the combined scores to a predetermined rule;
wherein the specified time frame is split into three sections and the first score and the second score are calculated for each section using:, score
