SYSTEMS AND METHODS FOR LIMITING WINCH OVERRUN

摘要

A retrieval system for a wireline drilling system having a winch, a wireline rope connected to the winch, and a core sampler connected to the wireline rope. The retrieval system includes a radio-frequency identification (RFID) transponder and a controller that, in response to receiving a wireless signal from the RFID transponder, automatically adjusts a speed at which the winch retrieves the core sampler.
