Abstract
A method of registering perforating guns in a tubing conveyed perforating assembly as set forth. On a tubing string, a TCP assembly is lowered in a cased well. In the tubing string, a logging cable supported radioactive logging tool is then moved along the well to controllably locate the formation of interest. After the depth of this formation is known, the tubing string is moved to reposition the TCP assembly in registry with the formation of interest. The logging tool is retrieved only partially and is then lowered to operative contact with the TCP assembly to provide a signal path for operation of a firing mechanism to fire the shaped charges to form perforations into the formation.
