Collar Locator

A logging device that detects casing or tubing collars for depths correlation purposes. The collar locator may be operated mechanically or electrically to produce a log showing the location of each casing or tubing collar within the wellbore. When properly interpreted, this log provides an accurate means for depths measurements in a wellbore.
