    Abstract: The articulated wireline hole finder is a modular device which attaches to the bottom of a wireline logging tool-string to aid conveyance down irregular shaped and/or deviated boreholes which possess features such as ledges, washouts, and contractions, that might otherwise terminate full descent of the tool-string to the bottom of the borehole and thereby compromise the wireline data acquisition objectives. Elements of the articulated wireline hole finder may include a low friction roller nose assembly and spacer sub, an articulated spring joint, that transfers tool-string weight and directs lateral movement of the roller nose towards hole center, and a pair of five arm centralizers that possess a wide dynamic range.
