Abstract
A fluid monitoring system comprises a data acquisition and control interface and one or more fluid measurement devices communicatively coupled to the data acquisition and control interface. The one or more fluid measurement devices are configured to detect amounts of fluids pumped into or exiting the well bore during cementing. The data acquisition and control interface receives a first set of data comprising calculated volumes and/or pressures of a flow of one or more fluids exiting a model well bore over a predetermined period of time based in part on a heat of reaction produced by the curing of a cement composition, and a second set of data comprising volumes and/or pressures of a flow of one or more fluids pumped into or exiting the well bore from the one or more fluid measurement devices. The data acquisition and control interface uses the first and second sets of data received to determine one or more characteristics of the cement composition.
