Improved slick line system with real-time surface display

Système perfectionné de ligne de tube à garnissage avec affichage en temps réel en surface

Verbesserte, mit Fett geschmierte Kabelanordnung zur Echtzeit-Oberflächenabbildung


An apparatus and method is provided whereby a small diameter, single conductor wireline is combined with standard slick line equipment to obtain "real-time" surface display from well logging tools. A helically formed, insulated conductor coextending within a conductive tube functionally replaces standard solid wire for lowering tools down into a wellbore and for transmitting tool-generated signals to a surface-located display.
