Method for using voxelated x-ray data to adaptively modify ultrasound inversion model geometry during cement evaluation

Abstract A combining mechanism for borehole logging tool data that uses density data from a logging tool to inform the geometry of an acoustic-based or ultrasound-based data inversion is provided, comprising: at least one mechanism for converting three 5 dimensional density data into a three-dimensional density model; at least one mechanism for converting three-dimensional density model into a three-dimensional acoustic impedance model; and, at least one mechanism for processing acoustic data using said three-dimensional acoustic impedance model to produce an interpretable data log. A method of using density data from a logging tool to inform the geometry of an acoustic .0 based or ultrasound-based data inversion is also provided, comprising: converting three dimensional density data into a three-dimensional density model; converting three dimensional density model into a three-dimensional acoustic impedance model; and, processing acoustic data using said three-dimensional acoustic impedance model to produce an interpretable data log.
