ABSTRACT:
A method and apparatus for estimating the time varying mechanical properties of a cement including propagating acoustic waves through a cement sample, measuring signals corresponding to the acoustic waves after they propagate in the sample, comparing attributes from the measured signals with corresponding attributes provided by a model accounting for at least initially estimated acoustic properties of the cement, using the differences between the measured and calculated signals to update the initially estimated acoustic properties of the material in the calculating model, using the differences between the measured and calculated signals, updating the initial acoustic properties in the model, processing N iterations of the comparison and updating either until the differences between measured and calculated signals are within a given tolerance factor or when the number i reaches a prescribed maximum and calculating the time varying mechanical properties of the cement from the final iterated acoustic properties.
