Previously, I wrote about choosing wire lines for a cable-tool drill rig. We would have three types: a drill line, a sand line and perhaps a casing line. Whatever size of rig and lines that we are using, these lines need to be cared for.
All steel cable will be purchased in a lubricated state. Small, individual wires that make up the line work against each other and need lubrication. The lubricant also protects the steel wires against rust and quick deterioration, especially when drilling in harsh conditions. There are lubricants available to re-lubricate wire lines after some service, but I have found these difficult to use and, in case of lubricants in a spray can, downright wasteful. An effective way to lubricate lines on the rig is to brush on heavy oils or even light grease. This works well for the drill and sand lines but can prove time consuming.
