Abstract
Systems, methods, and devices for evaluating proper cement installation in a well are provided. In one example, a method includes receiving acoustic cement evaluation data parameterized using a first parameterization. A subset of the acoustic cement evaluation data is compared to expected nominal values of the acoustic cement evaluation data. When the subset of the acoustic cement evaluation data does not substantially conform to the expected nominal values of the acoustic cement evaluation data, all or part of the acoustic cement evaluation data is corrected to cause the subset of the acoustic cement evaluation data to more closely match the expected nominal values of the acoustic cement evaluation data. The corrected acoustic cement evaluation data may be used to estimate a presence of solids, liquids, and/or gases behind the casing.
