Firstly, the error was estimated due to the wireline unit. So the normal wireline unit was changed with the service
company’s high tension logging system for deep wells and sticky hole conditions with heavy tool strings. The system
comprised of a standard wireline unit, a high-strength dual-drum capstan and high-strength wireline cable. The capstan
increased the pull that can be exerted on the wireline, so even heavy toolstrings can be retrieved, reducing the risk of sticking. |
