Abstract
A bond log analysis apparatus and system and method for use of the same are disclosed. In one embodiment, the system receives a Cement Bond Log (CBL) including a Variable Density Log (VDL) and at least one Secondary Data Track (SDT). The system conducts an initial analysis of the VDL to identify characteristics and patterns related to cement bonding conditions at a specified depth. If a possible discontinuity is identified, the system sequentially analyzes VDL data from adjacent depths to determine the vertical extent of the anomaly. For the identified vertical extent, the system performs a detailed analysis using SDT data to characterize the cement bonding issues. The system then synthesizes the VDL and SDT data to generate a report providing an analysis of the cement integrity around the wellbore casing. The method follows similar steps for bond log analysis.
