Our Slickline

The CWI family of GD™ – SUPA® slickline is engineered for oil, gas, and geothermal applications. Our slickline is manufactured in North America and the United Kingdom from alloys designed to provide a continuous 30,000 feet (9144 m) weld-free, bright finish wireline. We have corrosion-resistant lines designed to go downhole in sour and sweet environments. CWI slickline are also suitable for measuring-line / wireline and electro-mechanical (EM) cable.

Slickline Guidelines

To maximize the life of your CWI GD™-SUPA® slickline follow these guidelines:

• Confirm the wire is suitable for the expected well conditions. CWI experts can help you determine that.
• Use a Vernier Calliper to check the wire OD.
• Use new packing in the stuffing box and change the wire guides if they show signs of excessive wear.
• Use correct sized sheaves (rule of thumb – sheave diameter = 120 x wire OD.)
• Always lubricate the wire when running into the well.
• Never exceed the maximum allowed wire tension. This will be set at a maximum of 60% of the breaking load reported on your CWI issued test certification.
• Clean the wire pulled from the well; use a wireline wiper to remove well fluids.
• Always update the wire logbook with the wire cut-off and data from the operation.
