A device for carrying out at least one of measuring or servicing operations in a well, with the device including a rod which is stiff against compression and elastic in flexure and a measuring instrument fastened to an end of the rod. The rod includes a core having a flattened cross sectional shape adapted to provide the rod with a high flexibility in flexure in a first plane, with respect to a flexure in a plane orthogonal to the first plane. At least one energy or information transfer line is incorporated or embedded during manufacturing the core which is made of a composite material. A sheath embedded in the core so as to provide the rod a substantially cylindrical outer shape. The device is applicable to be used in a well producing an oil effluent.
