ABSTRACT:
The invention provides an improved wireline that comprises one or more insulated conductors contained within a smooth walled metal sheath; which improved wireline is satisfactory to perform all of the normal wireline operations in an earth borehole and particularly in very deep boreholes; and in which the sheath material of the wireline is a metal having a high yield strength to weight ratio, and the sheath is swaged into intimate contact with the inner insulated conductor or conductors, such that the weight of the inner conductor or conductors and insulation is effectively supported by the sheath.
