Abstract: This disclosure presents a process to determine an alignment parameter for geosteering a wellbore undergoing drilling operations. The process can receive one or more azimuthal image log data sets, one or more geology logs, and other input parameters. The image log data sets can be transformed to better approximate the geology logs, such as transforming a 3D representation to a 2D representation and flattening out curves represented in the original image log data. The geology logs or transformed image log data can then be moved to create an approximate alignment between the other log data. The movement, which can be a sliding movement, a linear movement, a tilting movement, an angling movement, or a rotating movement, can be used to determine the determined alignment parameter or final alignment parameter. The alignment parameter can be used as input into a geosteering system for the wellbore.
