Abstract: Systems and methods compute dysfunctions via amplitude envelopes that deviate from a mean (normal) state behavior. The envelope function is constructed from a recursive application of the maximum signal value within a given window size. The aforementioned operations are causal and computationally affordable as relative short moving windows are required to trail the current point. Therefore, the proposed envelope and dysfunction calculations are amenable for any source of data streams measured at high sample rates. The effectiveness of the computing is validated as representing multiple physics in real time field drilling operations.
