METHOD FOR MONITORING THE PROPERTIES OF A FLUID CEMENT COMPOSITION IN A FLOW PATH

摘要

Optical analysis systems may be useful for determining the properties of fluid cement compositions. For example, a method may include generating with an optical computing device a plurality of output signals corresponding to a plurality of time points and a characteristic of a fluid cement composition at a monitoring location within a flow path (404), the optical computing device having an electromagnetic radiation source(308) configured to optically interact with the fluid cement composition and an integrated computational element, wherein the integrated computational element is configured to produce and convey optically interacted light to a detector (324) which generates a plurality of output signals corresponding to the characteristic at a plurality of time points; receiving the plurality of output signals with a signal processor (442) communicably coupled to the detector; and determining a difference between at least two of the output signals (33ba, 336b) with the signal) processor.
