    摘要： There is provided a system and method for determining interwell communication in a hydrocarbon-producing field that has a plurality of wells. An exemplary method comprises determining communication relationships for the plurality of wells using a multivariate dynamic joint analysis algorithm based on data representing properties of each of the plurality of wells. The multivariate dynamic joint analysis algorithm may employ a self-response of each of the plurality of wells and an interwell response between combinations of the plurality of wells. Data representative of the communication relationships is provided.

    摘要： Systems and methods for multi-channel detection of an instability in a furnace comprising a plurality of detectors are disclosed. Each of a plurality of detectors provides a first measurement related to the plurality of burners when the furnace is operating in a stable condition. A stable signal component representation is determined based on the first measurement from each of the plurality of detectors. Each of a plurality of detectors provides a second measurement related to the plurality of burners when the furnace is operating in an unknown state. An unstable signal component representation is determined based on the stable signal component representation and a second measurement from each of the plurality of detectors. An instability is detected based on the unstable signal component representation and an instability threshold.

    摘要： Systems and methods for detecting an instability associated with at least one burner are disclosed. A detector measures a signal associated with a characteristic of the at least one burner. The signal is converted to a time-varying signal spectrum using at least one processor. An instability is detected based at least in part on the time-varying signal spectrum. The instability can be detected based on an instability indicator calculated based at least in part on the time-varying signal spectrum. A threshold can be associated with the instability indicator such that an instability is detected when the instability indicator is greater than the threshold.
