Abstract

A method for operating a wireline winch configured to convey a wireline coupled to a downhole tool disposed in a borehole penetrating the earth includes: receiving a first cumulative surface wireline tension limit for downhole wireline components; calculating a second cumulative surface wireline tension limit for surface components using wireline speed and surface equipment data; combining the first and the second cumulative surface wireline tension limits to provide a total cumulative surface wireline tension limit as a function of depth; presenting the total cumulative surface wireline tension limit as a function of depth and operating wireline tension values as a function of depth for the downhole tool to a user; performing an assessment of the operating wireline tension values as a function of depth versus the total cumulative surface wireline tension limit as a function of depth; and operating the wireline winch using the assessment and a winch controller.
