In oil and gas exploration, the term wireline broadly defines industry-specific methods, processes, and technologies that lower cables and wires into a wellbore. Wirelines are strong, thin lengths of wire or braided cable mounted on a powered reel. Typical wireline applications affix “logging tools” or instruments to a cable rigged to drilling platforms or trucks that, once attached, is lowered by the cable into oil well holes or natural gas reservoirs to perform diagnostics or to gather and transmit data. As a general descriptive term, wireline is also used interchangeably to describe the processes, techniques, cabling technologies, and systems used to conduct wireline operations.
