Claim 23:
24. A method for detecting the occurrence of an event at a well comprising:
recording a first set of measurements collected from the well; wherein the first set of measurements are collected from a sensor disposed on a drill bit comprising a receiver and a transmitter configured to communicate with an information handling system;
transmitting the recorded measurements to the information handling system for processing; wherein the information handling system is disposed on a surface of the earth;
processing the recorded measurements to provide a first set of data;
calculating a first score based on the first set of processed data;
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 based on a specified time frame; and
altering rates of penetration by adjusting the rate of advance of the drill bit based on the score comparison by an operator;
wherein the first score and the second score are calculated using:, score

wherein d is the first set of data collected or the second set of data collected;
wherein dset is a predetermined set limit; and
wherein mad() is a median absolute deviation between a normal difference between a simulated first set of measurements or a simulated second set of measurements and an actual first set of measurements or an actual second set of measurements.
