n pl: the characteristic patterns for various degrees of cement bonding between the casing and the borehole that appear on an oscilloscope display when a sonic cement bond log is made.

n: Logging in the cased hole, for example, cement bond log, casing caliper log, casing coupling log and other well loggings.

rotating the casing string during primary cementing to remove mud and improve primary cement bonding and isolation.

abbr: cement bond log.

cement bond log.

cement bond tool.

n: the adherence of casing to cement and cement to formation. When casing is run in a well, it is set, or bonded, to the formation by means of cement.

n: The formation and casing are binded with each other after cementing.

the strength and adherence of the cement to the pipe and the formation.

n: an acoustic logging method based on the fact that sound travels at different speeds through materials of different densities. The fact that sound travels faster through cement than through air can be used to determine whether the cement has bonded properly to the casing.

n: Reflect the quality of cement bond after cementing. Used to check cement job quality.

a sonic log that determines the top of the cement column and estimates the quality of the cement bond between the casing and the formation. Works on transmission of a sound wave and identifies areas that conduct the wave and those that do not (free pipe r

n: an acoustic survey or sonic-logging method that records the quality or hardness of the cement used in the annulus to bond the casing and the formation. Casing that is well bonded to the formation transmits an acoustic signal quickly;poorly bonded causing transmits a signal slowly. See acoustic survey. acoustic well logging.

n: See cement bond log.

n: Schlumberger wireline tool that provides a measure of casing to cement and cement to formation cement bond.

n: The creation of voids in the cement between the casing and the borehole, thereby reducing the effectiveness of the cement bond.
