n: See collar locator.

n: The logging trace formed by collar locator device measuring the position of casing collar.

CCL, a downhole log recording, given by magnetic deflection, of the location of couplings or other equipment.

abbr: casing collar log.

casing collar locator log.

n: A logging device for depth-correlation purposes, operated mechanically or magnetically to produce a log showing the location of each casing, tubing collar, or coupling in a well. It provides an accurate way to measure depth in a well.

n: see collar locatol:

n: A logging method of measuring the position of casing collar with collar locator device. It is also a reliable method of measuring well depth.

n: an elevator that is bored to match a square shouldered tool joint. collar locator n: a logging device used to determine accurately the depth of a well;the log measures and records the depth of each casing collar, or coupling, in a well. Since the length of each joint of casing is written down, along with the number of joints of casing that were put into the well, knowing the number and depth of the collars allows an accurate measure of well depth.

n: a kinds of simple and accurate tool that measures thye location of casing box coupling.

n: a length of drill or line pipe, tubing, or casing shorter than range 1 (18 feet or 6.26 metres for drill pipe) in length.

n: a short section of pipe used tospace out casing or tubing to reach the correct landing depths.

a short section of casing or tubing used as a depth identifier to a collar locator log or used at the top of the well when spacing out a string prior to hanging the string.
