    Abstract: A system for reservoir formation characterization with a downhole wireless telemetry system, including at least one sensor disposed along a tubular body; at least one sensor communications node placed along the tubular body and affixed to a wall of the tubular body, the sensor communications node being in communication with the at least one sensor and configured to receive signals therefrom; a topside communications node placed proximate a surface; a plurality of intermediate communications nodes spaced along the tubular body and attached to a wall of the tubular body, wherein the intermediate communications nodes are configured to transmit signals received from the at least one sensor communications node to the topside communications node in substantially a node-to-node arrangement; a receiver at the surface configured to receive signals from the topside communications node; and a topside data acquisition system structured and arranged to communicate with the topside communications node. A method for reservoir formation characterization is also provided.

    Abstract: 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.

    Abstract: Methods for determining the fouling propensity of a hydrocarbon stream and for reducing fouling are provided. In one method, the fouling propensity of a hydrocarbon stream is determined by obtaining a parameter value indicative of the fouling propensity at no less than two different temperatures, and an activation energy of fouling by the hydrocarbon stream is derived therefrom. In another method, the thus obtained parameter value at no less than two different temperatures and the activation energy are used to select proper heating fluids and operating temperature and to determine whether to add an antifoulant to the hydrocarbon stream to reduce fouling at a given temperature.
