Well logging involves the measurement of many physical parameters in the depths of an oil well and the continuous transmission of these measurements to the surface for processing and recording. Many of the techniques used are quite advanced. There is good prospect of using them to advantage in the oceans, because many of the parameters measured in these two regions are alike and because many of the environmental conditions encountered are similar. Measurements commonly made include, for example, temperature, conductivity, sound velocity and radioactivity. Data is recorded at the surface in analog form on film and, more recently, in digital form on magnetic tape. Other services are available too, such as the taking of fluid and solid samples. Unique hardware has been developed for use at high ambient pressure, including electrical connectors and swivels for multiconductor armored cables. In the area of cable handling gear, large-capacity smooth-control winches with low-noise slip rings are a significant development. This paper is devoted to discussing a number of the interesting aspects of the parallels between well logging and the marine sciences.
