It is available in single crystal form or the more rugged polycrystalline form (used in high vibration environments, e.g. wireline logging in the oil industry).
They cited the declining use of the service, as well as a desire to focus on their key businesses: broadband, wireless and wireline services.
Traditional activities are wireline operations for well logging, perforation and installing or pulling equipment like plugs and downhole safety valve inserts.

The logging tool, also called a sonde, is located at the bottom of the wireline.
If the tool is to become stuck in the well, the weak point is where the tool would first separate from the wireline.
Wireline depth correction for temperature and tension has been around since before the days of computer data acquisition, and is generally seen as reliable.
Nearly all wireline and wireless telecommunications companies utilize similar technologies today to transport near-real-time billing information.
