For use in a logging tool system positioned in a well borehole by a drill string and exposed to drilling fluid in the well, a connective apparatus is described enabling the logging tool system to be selectively connected to a conductor system in a wireline. The connective apparatus comprises: (a) a wet connector having: (1) a lower end located terminal means adapted to be connected to a logging tool system on a drill pipe conveyed logging system; (2) an upwardly facing first electrical mating means connected to the terminal means; (3) an upwardly facing first mechanical mating means; (b) a wireline supported overshot having: (1) means connecting to a wireline; (2) second electrical mating means; (3) second mechanical mating means; (c) wherein: (1) the overshot positions the first and second mechanical mating means for achieving positive mechanical connection after travel of the overshot through the drill pipe; (2) the first and second electrical mating means achieve electrical connection to provide an electrical path from the logging system to the wireline; (3) the positive mechanical connection avoids placing a mechanical load on the electrical mating means; (4) the overshot is retrievable along the drill pipe after release of the mechanical and electrical connections; (5) the wet connector electrical mating means is concentric within the upwardly facing first mechanical mating means; and (6) the first mechanical mating means includes a telescoping sleeve resiliently forced upwardly around the first electrical mating means and including means on the overshot for forcing the sleeve downwardly to expose the upwardly facing first electrical mating means.
