Abstract

A well logging apparatus is provided having downhole well data acquired by a sensor (406), transmitted to the surface via complementary modems (410 and 418), and conveyed to the surface modem (418) via a data cable (412) linking the modems, the cable (412) having at least one pair of insulated conductors (102 and 104) wound in a substantially helical twist, an insulation sheath (108) surrounding the twisted pair of conductors (102 and 104) and a tensile load carrier (112) surrounding the insulation sheath (108), the load carrier comprising a sheath of tensile load carrying filaments.
