Here's a response from one of our COIN registered non-members, Chris White.
As a result of an extremely serious incident which I experienced many years ago on a SNS gas well, I would most strongly advise against deploying any logging tools on braided cable in a potentially solids-laden well stream environment.
The logging cable is coated in pressure-retaining grease to which solids particles adhere. The cable exits the surface pressure control equipment via a set of flow tubes which have an internal diameter approximately 0.001” larger than the cable passing through it. The axial gap between cable and flow tube is filled with grease at a pressure above the wellhead pressure to provides a seal against well pressure.
Solid particles stuck to the cable grease will accumulate below the flow-tube and become jammed between cable and flow-tube. Because the cable is helically wound, the cable will start to twist as it is recovered from the well thus torqueing-up the cable and ultimately preventing the cable from passing through the flow-tubes, leaving cable and/or toolstring stuck across the Production Tree and downhole safety valve preventing them from closing.
In my case, ultimately the well was killed to allow the situation to be remediated, but not until a major incident had occurred resulting in serious personal injuries, loss of containment, damage to equipment, and loss of production. Additionally, the logging cable had to be scrapped as the section that had been recovered before it became jammed had been torqued-up on the winch drum.
In Paul’s case the noise-log tools should be deployed as part of a memory toolstring on slickline or coil tubing, however if real-time surface read-out is required, or if the logging tools cannot be incorporated in a memory toolstring, then deployment should be via e-coil.
Hope this helps
