Abstract
A method and apparatus for conducting logging or perforating operation in a borehole, particularly a deviated borehole, includes lowering a length of drill pipe having the well-logging tool, or well bore perforator, releasably mounted thereon into the borehole. An extension member, which is also lowered through the drill pipe, is secured to the well-logging tool, or well bore perforator, and releases it from the drill pipe, whereupon the extension member and well-logging tool or well bore perforator are moved through the borehole. The apparatus includes a latching sub mounted to the end of the length of drill pipe, and a latching head releasably mounted within the latching sub for releasably holding a well-logging tool or well bore perforator within the latching sub.
